User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20160105164030 Steps to reproduce: While writing a message I highlighted a piece of text, then clicked on Format --> Text Style --> Italic to italicize it. I then wanted to change part of it back to normal text, so I highlighted that part and clicked on format --> Text Style --> Italic to toggle it back to normal text style. (I am running Thunderbird on a Windows 10 desktop machine. When I click on "About Thunderbird", the release number that appears is 38.5.1, and it says "Thunderbird is up to date.") Actual results: The highlighted portion of the text remained in Italic. Expected results: The highlighted portion of the text should have toggled back from Italic to normal text. That is what happens when i go through the same process with "Bold" or "Underline" text styles, for example.
Gomer, Are you seeing this also in version 45?
I'm not Gomer, but yes. I'm seeing it in 45.7.0
