This was causing state pollution in the new selection. I can't see why
this needs to happen when a selection changes to another.
This fixes https://github.com/ppy/osu/issues/30839 and also the same
issue happening for the new combo toggle.
Tests all seem to pass, and I can't immediately find anything broken,
but YMMV.
Queuing up requests on change to `api.LocalUser` is bad because the API
state is updated after `LocalUser` is updated, therefore we have to
schhhhhedullllllllleeeeeeeeeeeeeeee.
Users have asked for this multiple times since last release.
Not sure on the best default value, but I'm going with the
stable/classic one, at least for the initial release to avoid needing
migrations.
In the future we may reconsider this for new users.
