Yuan, feel free to steal this. Just a reminder for me to take a look at it.

Jan, Is it ok for me to take this bug? I'm looking to pick up some keyboard work.

Yeah, sure, you're aware that this is a Gecko bug?

On second thought, Maybe it isn't. :-)

Thanks Jan, I think there may be a gaia solution to this issue. I will attach a pr with my notes and changes.

Comment on attachment 819198 [details] Github pull request Stealing review as David is already loaded. Code looks good, some small nits in GitHub. If you have a smart idea about how to prevent calling |deactivate| a lot of times that'd be welcome. The travis build fails over a marionette test that seems unrelated, can you rebase against master and see if the error disappears? If all good and nits addressed please ask for review again. Thanks!

Plus it and assign milestone to 1.2 C4 (Nov. 8)
