Viewport reacts to input in other docks/tools

[mhilbrunner]

Operating system or device, Godot version, GPU Model and driver (if graphics related):
Windows 7 x64, master@18d3ha0c

Issue description:
Pressing W, A, S, D is always registered in the viewport, even if other docks or tools are focused and used. (Example: Renaming things, filtering the scene node list or saving.)

Steps to reproduce:

1. Open Godot and create a new scene
2. Move view in viewport with W, A, S, D shortcuts
3. Enter something using those same keys somewhere else (e.g. filtering, or in the save dialog)
4. Observe that the viewport still reacts to those keypresses

Is it WASD in particular? These are polled differently with direct input when freelook is active. However, freelook can only be active when RMB is pressed and the viewport has focus, which both shouldn't be the case in this save dialog...

[mhilbrunner]

Only found it working (or rather, not working) with WASD, so that may be the case.

duplicated of #11556 ?
I think they are definitely related.

I just tried it but couldn't reproduce the issue, can you confirm that it's fixed?

Since #11556 seems to be platform-specific: I'm testing on Mageia 6 x86_64 (Linux, Plasma 5).

Is this possibly related to #15199 ? Probably not. I just bring it up because both involve input misdirection amongst Godot sub/windows.

Can confirm this no longer happens with current master. Fixed.
