T-146: Cursor occasionally wondering out of the game window when playing in Windowed mode (without any UI's that release the mouse active)

Issue Details

Platform:PC

Context:

Clicking in and out of Trove kind of frequently, and one time I clicked back in, my cursor carried over to my second monitor and the next click I performed unfocused the Trove window.

Expected:

The cursor to not be capable of leaving the trove window when you do not have a UI that unlocks the cursor open or are not holding the "Release Mouse" hotkey

Reproduce:

When playing in Windowed mode, cursor will sometimes not be restricted to the game window (that is, the cursor will leave the game window when you do not have any UI open, and are currently controlling the camera).
- I don't have an easy exact repro for this one. Times this has happened for me are usually when I am clicking in and out of the game window frequently, usually with a UI being open to unlock the cursor so I can click out. Clicking back into the game window and immediately moving (forcing the UI to close) sometimes allows my cursor to wonder off until opening and closing another UI. I suspect it may be an issue with multithreading as I was not able to get this to occur in my (attempted) tests to find a repro without multithreading enabled.
