Closes https://github.com/ppy/osu/issues/17965.
Note that this will cause a second osu! icon to appear after running the
application (after any update). As per the inline comment, this will
eventually be resolved via https://github.com/clowd/Clowd.Squirrel/issues/24.
I do think having context menus working is more important than duplicate
icons.
Note that for anyone who already has a pinned taskbar icon, it will need
to be manually unpinned and repinned after a future update to actually
fix this issue.
Thanks to @caesay for help with investigation.
With 0 delay, if the `SettingsToolboxGroup` has been contracted via
button, there's no chance to be able to expand it via button again.
This is temporary at best just to keep things working somewhat, not sure
if the expansion logic will still be required in editor redesign, so
deciding to roll with it for now.
Might as well inline, but I feel like it will require adding the same
comment across all usages, because just `State.Value = Hidden` in an
until step feels off, dunno.
