📄 Description

Summary of the Pull Request

The issue seems to be how SwapChainScaleChanged gets fired and attempts to tell the renderer
to UpdateDPI when the renderer is gone. So, as a quick bandaid, we'll put a quick check to only do the thing if the renderer is alive.

PR Checklist

Validation Steps Performed

Held my new tab button for about thirty seconds then held the close tab button until all tabs closed without a crash.
