Windows Terminal version (or Windows build number)

10.0.19043.1165

Other Software

NA

Steps to reproduce

Have a simple app that will set the buffer size to window size right after any resize. Then use the cursor to grow and shrink the window constantly for 15 - 30s. Holding F11 does the trick too.

Expected Behavior

Console should not crash if someone resizes window in a playful way with cursor.

Actual Behavior

When you use the cursor to grow and shrink the window constantly for 15 - 30s console will crash.
