Probably a regression from the recent changes to e.me?
Dale, could you take a look please?  or direct it to the appropriate person?

Yeh have noticed this, shouldnt be caused by any e.me changes but will take a look

Hrm, maybe something else on master.

Note : I tested on 3.0 (latest) and 2.2 (latest):

I vaguely remember this being a problem before since a click went through the keyboard and hit something on the search app behind it

Tim I am looking into the search app to see if anything could be stealing focus, but do you know of any keyboard issues that may cause this?

[Dale Harvey (:daleharvey)]

So if the search app does nothing at all, this still happens. I remember someone putting a .focus() conditional around somewhere, this bug happens when you enter the first characters in the rocketbar, during that time the search app gets displayed so I think when we show the search window it is getting a .focus called somewhere

If I remove the |this.results.classList.remove('hidden');| from https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/rocketbar.js#L365. Then this issue goes away. Switching needinfo from Tim to Alive since it looks like its a window management issue.

If this isnt on 2.2, then it seems like its possibly a gecko issue?

[Tim Guan-tin Chien [:timdream] (please needinfo)]

This would be a dup of bug 1129344 if it only happens on Rocket bar.

Comment 8

[Dale Harvey (:daleharvey)]

Yeh that has the same reproduction steps as I was investigating
