Issue With Play Inside Editor & Mouse

I was seeing an issue with playing inside the editor (while using the UFPS asset), where the mouse is not captured when you click play, so you can click the buttons if you're inside the window, but you can't look around. This works fine on Windows, wine, and on an exported Linux build from this editor.

Rest of the thing worked very well, was able to download an asset very easily and installation was well done.

 

Same thing here, can't capture the mouse as it works on windows editor
