Weird font change edit result

Working on a new post at Our strategy and its critics — Economic Networks

I changed the font size via a font sixe=“13” tag. (Might have been 16, I can’t see the tag anymore.)

Now when I click the Edit button I only see the headline, nothing else. No text, no font tag.

What happened? What did I do wrong?

I’m working in Firefox on a Linux variant OS.

Ok, fixed. Apparently I had changed to the “Rich Editor” without knowing it. When I switched back to the “Plain Eidtor”, all was well. Sorry for the false alarm…
