[Step] - click on the "test case" attachment. - focus the contenteditable="true" element, ie the grey box at the end of the page - observe the caret position [Expected] - As this element has a `text-align="right"` the caret should be on the right. [Actual] - The caret is on the left, and jumps to the right as soon as we begin typing.

Hey Julien, this test case is basically a stripped down version of the .recipient[contenteditable] of the sms app. I thought you might want to see this. I'm filling this bug because, although the symptoms are the same, I couldn't reproduce with the example in https://bugzilla.mozilla.org/show_bug.cgi?id=1103011 any more. If this get fixed, we might be able to get rid of all the workaround in recipients.css \o/

also NI Simon, as he was the assignee for bug 1103011.

I think you can just attach this attachment in bug 1103011 and obsolete the old one. Then dupe this bug there. I still see weird things with the old one (for exemple using "suppr" with the caret at "start", the caret moves, but shouldn't), but I agree with you, the issue is not that apparent anymore on the old testvcase.
