[gaia-header] trigger the reformat only once even if several mutations happen, for the same heading
This happens when there is a nested markup in a gaia-header and we're changing several elements at once.
I still need to test properly the change. This happens especially in the SMS app, in the new message panel, when entering recipients. One part of the issue is bug 1109801, and I also think that l10n.js has the same issue with its MutationObserver.

Comment on attachment 8534524 [details] [review] gaia-header github PR Hey Guillaume, I don't have a good idea to do a unit test for this. Especially I couldn't reproduce the issue using a more synthetic testcase in jsbin... (see http://jsbin.com/jujuvavura/1/edit?html,js,console) so I don't know how to reproduce in a test :/

Oh, funnily, I reproduce in this jsbin when I just load it and it autoruns, but not when I click on "run JS". I don't know why.
Julien, I don't think you can reliably use jsbin for that. The reason why you see 2 vs 1 mutations is because jsbin is adding/removing scripts. To see that, just do "console.log(mutations[i]);" in your loop and you'll see added/removed nodes. Can you create a minimized testcase that works in a browser? The one from jsbin does not reproduce for me.
Yep I'll try; on the device and in the SMS app, I admit it happened on places I didn't expect it to happen, but didn't on the places I did expect :) So likely I don't understand how this is working ;)
Comment on attachment 8534524 [details] [review] gaia-header github PR Julien, try to replace the `/edit?blabla` in the URL by `/quiet` in jsbin and you'll just get the HTML and JS loaded as a regular HTML page. Apart from that, using Set to dedupe the elements looks good to me, so f+. Waiting on tests before the review.

Comment on attachment 8534524 [details] [review] gaia-header github PR Hey Guillaume, I managed to write a test that's failing with master and working with my code. Good thing: it also exercizes the whole mutation handling :) My previous issues were indeed directly caused by jsbin. Testing using a plain HTML file showed me it was working as I expected.

We should consider making it a feature blocker if this improves launch time.
feature-b2g: --- → 2.2?

Since it's landed to master, +'ed this one.
feature-b2g: 2.2? → 2.2+
note that it's landed to gaia-header master only, not gaia master yet :)
Carrying over r=gmarty Waiting for a try run.

Hi Julien, do you think we can take this patch to improve sms perfromance on 2.1? I found gaia-header version has big gap in between, would that be a problem if we uplift this?
Hey Sherman, I'd suggest to wait for bug 1089920 and then uplift all of this.
Cool, thank you Juilen :)
