almost impossible to edit .mdc rule files since (while typing) keyboard input focus jumps back up into the description input field ( at the end of the existing description string ) every 2 to 4 seconds. The context window flickers when that happens.
Also the AI hints are lost ( normal .md file editing works fine )
also some markdown syntax beautification is lost ( compared to .md files )
Update: seems to be related to autosave. When autosave is turned off ( manual save) globally or specifically for markdown files in the vsc settings, then the issue goes away.
