This is some bug in Flow (that is really hard to debug, I can't get it
to exit at all) but we can work around it for a minor visual impact. It
seems to me allow the reaction list to become slightly larger, but
that's about it.
BUG: 504344
FIXED-IN: 25.12.2
The devices entry gone (not even Element has this) and so is the logout
action. The Switch account menu item is moved to the bottom so its
easier to access by mouse. The "Open Secret Backup" is moved under
Security settings where it lives next to the other crypto-related
settings.
This is due to some kind of bug in ListView that never resettles
properly for bottom-to-top views. This can arise when the pinned message
is loaded (because that squishes the view) or the window is resized
(because that also resizes the view.)
We can work around it by assuming the following:
1. The RoomPage knows the window is resizing because it gets its height
changed before TimelineView.
2. The first height change can be a marker to position the view at the
beginning.
This fixes the issue for me, I did the following in order to test this:
* Switch between many rooms, especially ones with a pinned message. Now
all of them start at the bottom as they should.
* Resize the window, ensure that if you scrolled it stays around that
position - otherwise it sticks at the bottom.
I found that 50% of the time, NeoChat won't restore the last space but
instead get stuck at Home. Even worse, it will overwrite Home's last
opened room with the one from the space - resulting in really buggy
behavior.
The reason why this happens is partly due to the space hierarchy cache
(I think) but that's not the real problem in my opinion. During
setCurrentSpace, we needlessly update the last space & room config
despite us being the ones already reading it.
In addition to that I also refactored this code a bit to be more
consolidated and readable.
This fixes the annoying "I just scrolled down to the bottom, how come
NeoChat doesn't think I did?"
From what I can tell this is also ListView bug (or something caused by
our style/Kirigami) that creates cases like contentY being -643.2 (for a
ListView of height 643) thus that's not "at Y's end". For our case
though, we don't care and can safely round it.
