Intends to fix test failures as seen in https://github.com/ppy/osu/actions/runs/6692350567/job/18181352642#step:5:129
This is what happens if you carelessly fire and forget.
The working theory (that I'm not sure I have the tools to conclusively
confirm) is that the async write from the key binding changing could
fire _after_ the section is reset.
I briefly considered having the test wait for the change, but given that
the entirety of the surrounding flow is using sync operations, this just
looks like a bug to me. And there's no real sane way to inject async
into that flow due to dependence on `OsuButton.Action`.
