`SkipWhile()` in this context does not correctly ensure that
`ElementAtOrDefault(1)` is not a protected track. An explicit `Where()`
does.
Spotted accidentally when I noticed that skipping to next track can
select a protected track, but skipping to previous cannot.
RFC. Closes https://github.com/ppy/osu/issues/18169.
Implements the given proposal of keeping the current stable order but
adding a shuffle facility to the now playing overlay, and enabling it by
default.
There are more changes I want to make here but I'd like this to get
discussion first, because I am likely to continue putting this sort of
selection logic into `MusicController` and I just want to confirm nobody
is going to have a problem with that.
In particular this is not sharing the randomisation implementation with
beatmap carousel because it doesn't generalise nicely (song select cares
about the particular *beatmap difficulties* selected to rewind properly,
while the music controller only cares about picking a *beatmap set*).
In testing I can't find a reason for this to exist. Blaming back shows
that it existed before we had `AllowTrackControl` and was likely being
used as a stop-gap measure to achieve the same thing. It's existed since
over 6 years ago.
Let's give removing it a try to fix some usability concerns?
Closes https://github.com/ppy/osu/issues/29563.
This changes the editor to track the current track as it is *loaded* by
`MusicController`, rather than haphazardly following the current global
`WorkingBeatmap` (with a potentially unloaded track) or relying on local
immediate-load behaviour (as implemented in `ResourcesSection`).
This avoids any blocking overhead caused by a backlogged audio thread.
Test seem to pass so might be okay?
Note that order is still guaranteed due to the `ensureUpdateThread`
queueing system framework-side.
Isolates `CurrentTrack` from being directly adjusted by the mod, which could lead to issues depending on how the mod adds adjustments (i.e. `ModTimeRamp`, which adds adjustments based on changes to a setting bindable).
