In-game leaderboards are wrong if switching to another map/diff and entering play too fast

Game behaviour

Bug description

1. Have a map selected
2. Select a different map/diff, and immediately enter gameplay (or even autoplay)
3. Wrong leaderboard, it's the previously selected map instead

This isn't an issue if you don't enter gameplay too fast, but I'm prone to do that.

I would suggest to start the issue title to Song Select V2

There's a debounce at song select before the leaderboard is updated. One would hope that this doesn't affect gameplay (and gameplay does a potentially-redundant re-request for correct data), but we should also consider adding a force RunTask of the pending debounce before entering gameplay, probably around here:
