Dean Herbert 0c11fe7413 Fix toast popups spamming samples when adjusting osu!mania scroll speed during gameplay
Not the most robust of fixes, but as per the reasoning described in the
issue thread, a proper fix will take considerably more effort. This
intends to fix the issue first and foremost, as it sounds so bad I'd
want to mute my sound before adjusting currently.

Closes #15718.
