menu scroll problem

When you go to any kind of rule and choose “Copy from other application” for it and have many rules already - the menu don’t scroll at all (it opening for all screen height): mouse scroll not work and when you use keyboard arrows - it will go somewhere off-screen for other menu entries, but menu still don’t move.

I don’t really know at what point this start happening.

Why nobody comment this issue ??? - It is really annoying one that prevents from using “Copy from other application” as I have many applications - the list is huge.

Look at this screenshot from the top of the screen to bottom:
