Markdown preview is not visualized if file extension is changed with MD panel open #107
Description
Steps:
- open any TXT file
- open MD preview pane
- observe error message "file format not supported"
- rename from Notepad++ the open file extension (e,g. right click on filename tab and change .txt to .md)
Expected: MD preview is now shown
Observed: no update in MD preview, error message persists. Need to reload the MD pane.
I believe this could be a minor usability improvement.
