"Paste as Plain Text" greyed out

Operating system

Linux

Joplin version

2.13.8

Desktop version info

Joplin 2.13.8 (prod, linux) as appimage

Editor

Markdown Editor

What issue do you have?

Ctrl-Shift-V is shown in the menu, but in grey and not working.
In the options/settings it looks like activated options.

How can I activate it?

From looking at the app it seems that this is a Rich-Text Editor command. With the Markdown editor being a text only editor, pretty much any paste will be "text".

Indeed, here on the Linux version, the 'paste as text' menu is greyed when in markdown editor, and isn't greyed when I switch to the other one...
