📄 Description

See https://github.com/microsoft/terminal/issues/12176#issuecomment-1199488906, and MSFT:39723014.

I have literally no idea how to repro this one, or debug it. The dump I looked at looked like there was a SwapChainScaleChanged that was being dispatched as the app was tearing down. The ControlCore had started closing, but the TermControl hadn't yet. Apparently, just none of the _refreshSizeUnderLock callers checked if we were already closing.

All the callers appear to be on the main thread.

Closes #12176

Since there's no real way for me to repro this manually, I'm thinking we fire this fix off to the OS terminal build, where we'll pretty quickly be able to see if this fixed it or not.
