Device: Unagi Build: B2G 18 12/19/2012 Steps: 1. Install a privileged app off of marketplace - https://marketplace-dev.allizom.org/app/privileged-app-test/?src=mkt-search 2. When you confirm installation, move back to the homescreen and wait for the confirmation message to disappear Expected: The confirmation message should go completely off screen. Actual: See screenshot. The confirmation message border remains partially on screen. Reproducible on every single app install.

I think that this is caused by Bug 822231 which prevents animation and transition events from being sent. Hopefully this will land soon as the fixes are nearly ready.

We can see in [1] that indeed we use an animation event to make the banner disappear. [1] https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/system_banner.js

I could mark this bug as duplicate of 822231 but I prefer keep it open so that we'll remember to check that it is fixed as well.

QA Wanted for retest. If you get to testing this first, feel free to comment on the results.

Can't reproduce anymore. Fixed by bug 822231 apparently then.
