In general we're doing things correctly so the realm file shouldn't
expand (unless mass deletions are made from it), but this is a nice way
to manually confirm the behaviour.
Sometimes if using realm studio with osu! running, for instance, the
realm file size can blow out of proportion. This will recover from such
cases.
Note that calling `RealmFactory.Compact` itself is not enough, as it
will fail unless all instances of the realm have been closed.
The tests were relying on the `RulesetID` being set to 0 in the example
beatmap, even though the ruleset *instance* was set to ID 5.
This explicitly adds that 0 value to show intent, and also removes the
incorrect specification of 5 (which would cause the convert filter tests
to fail).
Also updates the filter code to use `OnlineID`, which is required in
realm changes.
Previously the slider path length would be snapped using the current
beat snap setting on *every* change of the slider path. As it turns out
this is unexpected behaviour in some situations (e.g. when reversing a
path, which is expected to preserve the previous duration, even though
the slider may be technically "unsnapped" at that point in time due to a
different beat snap setting being selected afterwards).
While displaying replays, the colour of the toolbox toggle button would
not match the actual state of the rest of the toolbox, i.e. both buttons
would be white, even though the "playback settings" section was expanded
and as such should have a yellow toggle button.
In the case of the replay player, the failure scenario was as follows:
1. `SettingsToolboxGroup` calls `updateExpanded()` in its BDL to update
the initial state of the toolbox, including the toggle button
colour, by adding a colour fade transform.
2. An ancestor of both the toolbox groups - `PlayerSettingsOverlay`,
which is a `VisibilityContainer` - calls `FinishTransforms(true)` in
its `LoadCompleteAsync()`, therefore instantly applying the colour
from point (1) to the toggle button instantly.
3. However, `IconButton` inherits from `OsuAnimatedButton`. And
`OsuAnimatedButton` changes its colour in `LoadComplete()`, therefore
undoing the instant application from point (2).
This conjunction of circumstances is instrumental to reproducing the
bug, because if the `FinishTransforms(true)` call wasn't there, point
(3) wouldn't matter - the transform would get applied at some
indeterminate point in the future, ignoring the write from
`OsuAnimatedButton`.
As for the fix, move the `updateExpanded()` call in
`SettingsToolboxGroup` to `LoadComplete()` to avoid the above
unfortunate order. Applying initial visual state in `LoadComplete()` is
the idiomatic style of doing things these days anyhow.
