Topic: Backspace in command mode alters text

If I start a search and replace command and use backspace to alter what I've typed the underlying text gets changed. This GIF https://1drv.ms/u/s!Aj7pYEj2vnD8hY91OzTmiGh7AFIAnA demonstrates the behavior.

Is this a known issue?

I'm using ViEmu 3.9.1 and version 16.2.0 of Visual Studio 2019, although I've noticed it for a few versions.
