I recently submitted a job application on Careers, and I wanted to make use of the "italic text" feature that was built in to the cover letter edit box.
It seemed to work well while I was editing the cover letter, however when I went back to make a change later (and during the review step), the italics had disappeared and the spacing around the italicized words was gone.
Also, I tried using the keyboard shortcut CTRL+I instead of the icon, and while the mode toggling worked, when I left italic mode the italicized word I had just written became un-italicized (this was in the editor, before preview mode). The spacing remained normal. Not sure if this is a bug or misfeature. This is independent from the bug outlined in the above paragraph.
I am using Google Chrome (latest as of question posting).
