Subject: [PATCH] Fixes runtimes in fit_viewport when user has the game
 minimized (#89802)

## About The Pull Request

Winget returns 0x0 size when the window is minimized, and it can be set
to 0x0 via external tools as well. In this case we should just abort
fit_viewport to prevent runtimes.

## Changelog

Not player facing
