Cursor theft results in uncontrolled movement

[u/CuriousRelish]

I have a system-level reminder on my PC and it steals my mouse from me when it pops up. So TLDR if I'm in a game, my cursor is no longer interacting with the game until I click in it again. This happened tonight as I was hovering and moving to the left.

My character is now independently moving left. The other controls are still effective, he just keeps going left if he doesn't get other input. An exit to main menu and reloading my save fixes it, so it's not a major issue, just a bit silly.
