Bypass Rack Windows Alt's behaviour on a specific module rect?

[DerozerDSP (Derozer)]

@Squinky

but you would probably have to make some widget be a child or rack itself.

I fear neither this will work. Tried to do this (so appending a widget to rack on top, follow @stoermelder trick on Stroke):

APP->scene->rack->addChild(new Test());

But it still call ScrollWidget widgets methods first (so its onButton(), which will consume and return). Using addChildBottom instead seems the same (it intercepts always ScrollWidget first).
