Yeah, I looked into that - way too complicated.

I'd go with the principle of least surprise here.

If there's only a small round button and the rest of that horizontal area
is visible "below" it, then the user will likely expect to be able to
interact with the button by "touching" the button and with what's shown
"below" it, otherwise.

Current Subsurface-mobile APKs are based on a forked version of
mobilecomponents (again) which implement just that.
