Shift+Tab (reverse indentation) not working in admin

I'm using linux Mint, Firefox.
Whether by an individual line or by a paragraph shift+tab does not reverse indent (
shift indent works for both)

So I end up editing on a notepad and pasting it into the grav content.
Any suggestions?

@gravclr, I cannot reproduce the issue. Using Chrome on Windows 11, tab and shift+tab work as expected in Admin.

Note:

• As mentioned in your previous post, indentation has a meaning in Markdown and may lead to unexpected behaviours.
• Also as mentioned in your previous post, using HTML in Markdown is often a smell of incorrect use of Markdown and templates.
