Issue description

Not sure if its me missing something or it shouldn't be used in tool context in the first place but i'm reporting it just in case.

I have Area2D node in SubViewport node, while its launched normally as game everything works as intended, it detects every button and motion event from mouse. The issue starts when the same scene gets attached to editor dock, now it only fires one mouse event motion when it enters the area, no extra signals when mouse is moved inside/buttons are clicked/mouse exits area.

I doubt anything is blocking inputs as it works in 'normal game mode' and that one input goes through.
If the issue is on my side i'd appreciate some guidance how to resolve it

Thank you for your time

Steps to reproduce
