If they existed before, then this is fix-optional for 52. If they exist only after our contextual feedback on password changes, then this is 52 affected.
See comment 1.
After rebasing to the following commit, the issue can't be reproduced, so I close it at this moment. http://hg.mozilla.org/mozilla-central/rev/d192a99be4b4
BTW, I can't reproduce it in Firefox Developer Edition 52 as well.
Tested on Ubuntu 16.04 with FF Nighlty 53.0a1 (2017-01-13) and I can't reproduce this.
