Could you provide an example of a device/OS where this patch is currently required? The current changelist requires code-style fixes, but it would be useful to verify where this is breaking first :pineapple:

I'm going to close this one since it's been a while.

@taurafigueiredo If this is still affecting you, could you open an issue with a reproducible test case and link back to this PR? I'm also a bit confused as to what's going on here; this looks like a hack for a problem higher up in the stack. Maybe the issue is really in paper-drawer-panel?
