- Make sure the connection to the room's chatBoxEditIdChanged signal is made so that the edit box gets filled.
- Make sure the minimum height and preferred width are available to the loader so they can be set and dynamically updated.
BUG: 465934
Update linkpreviewer to minimise the number of resizes.
- There is now a placeholder loading element to hold space while the data is obtained
- The component starts with a set size but can be expanded to see the whole item.
- The expand/contract button is only visible on hover
- The default size is picked to show 3 lines of text (1 heading and 2 description, 2 heading and 1 description, etc)
This is designed to help with the timeline scroll jumping CCBUG: 463235 by minimizing the amount of resizing for items in the timeline.

Implement folding sections for multiple consecutive state events. This also reworks some of the aggregated text output:
- Only new days cause a new section
- The aggregated text starts with either a single username or n users
- If the same user did the same action mutltiple times it will be in the aggregated text a user did x n times
- When there are multiple authors in a block with multiple state event types it will use or rather than and before the last event. e.g 3 user left the room or joined the room.

Implements network/neochat#90
This patch fixes two key issues:
* `?` is considered part of the URL, even if there might not be anything past it. I've seen people now putting spaces after URLs to get around this issue.
* `)` is also part of the URL, as well as `:` despite those not being valid characters at the end of URLs.
Improve the initial resizing of an image in the timeline by always looking to see whether sourcesize or image.info is populated first.
This allows the actual size of the image to be calculated as soon as possible while still maintaining the fix fo CCBUG: 460205
May also help CCBUG: 463235 I need help testing this it currently no longer happens for me.
- Update from deprecated readMarkerEventId to lastFullyReadEventId for quotient 0.7.
- Removed duplicate code for marking read from the read marker delegate.
- Make sure that mark as read only trigger at the end of the timeline
- Allow the read marker to be highlighted when jumped to
Make sure that the emote name is added inside the first paragraph rather than as an additional one.
Note alternate to network/neochat!632 because I didn'y realise @tfella had done a patch
CCBUG: 461837
Use animated images in imageDelegate and FullScreenImage so that animated images can be viewed.
Note webp animated images don't work this is a bug with qt see https://bugreports.qt.io/browse/QTBUG-70245
Update the base item in the timeline container to be a column layout. This means that all the items can be laid out automatically without the need to set lots of manual settings and anchoring.
The overall height calculation for the delegate is vastly simplified (in fact it is removed) which deals with the fact that there were still instances where the manual calculation didn't work e.g. a delegate with a reaction followed by another message from the same user didn't give the correct bottom margin (see below)

This also improves upon the recently changed hover highlight behaviour. The previous patched moved it to cover the avatar as well as the bubble however it also covered the section and reaction when present which didn't look good. The highlight now only covers the avatar and bubble

after:

This also cleans up some of the margins in both bubble and compact to ensure consistency.
Set max size to gridUnits * 30. The aim is to allow them to be generally bigger than bubble mode but not so huge that they take up the entire screen
BUG: 454878
**Updated**
Add a section label at the top which shows the date label of the next section up. This means that the user will always be able to see the date of all messages on screen.

From the feedback given I've added a background at the top. I also added an underline to the heading which applies both at the top and in the listView since they use the same component. I added it originally for the top because I felt it looked a bit weird having messages appear from behind a heading background the same colour as the listView background.
Note: I know the gaps between messages are not right. I had to set the spacing in the listView to 0 to prevent itemAt returning null. I plan to add it back in as part of the delegate code before it would be merge.
