Game window loses focus on start, must left-click first to enable inputs

System information

Windows 10

Issue description

Sometimes when running a scene, the game loses focus, keyboard doesn't work and mouse events get ignored, you must left click to focus on the game window and start playing.

Steps to reproduce

Run the scene several times. Sometimes it will work just fine, others you will try to move with WASD or move the mouse and nothing will happen. Left click if that happens to "solve" the issue.
These are the settings for the Window.

how fix this?

Having "Resizeable" unchecked is what causes this. Turning it back on will make it focus on startup.

If you want to keep this a thing, have it unchecked by default then run this code in a ready function:
DisplayServer.window_set_flag(DisplayServer.WINDOW_FLAG_RESIZE_DISABLED, true)

I had an issue where Windows' taskbar showed on top of the game on exclusive fullscreen mode, even after the player clicks on the window to give it focus.

Disabling "Resizeable" fixed that too.
