Bug (Case 1184172) Regression: Game View loses focus if mouse hovers over some editor UI

In playmode, Input.GetKey stops working if the mouse hovers over some editor UI controls, because the Game View loses its focus.

The editor UI seems to steal the input focus from the Game View and Input.GetKey no longer works, until you click inside the Game View again.

You can also observe that the highlighted tab changes.

Reproduce

• Open attached project
• Open SampleScene
• Press Play
• Hold down F key
• Move mouse over Console search field or Hierarchy

Actual
The input focus is stolen from the Game View and Input.GetKey no longer works.

Expected
Hovering over editor UI elements should not steal the input focus from Game View during playmode.

Note
I'm working on a first person shooter (keyboard/mouse controls) and this issue makes testing/playing in the editor very difficult, because input randomly stops working when moving the mouse.

 

I was unable to replicate this problem in Unity 2020.1.0a3.
