Comment on attachment 743650 [details] Pointer to Github pull request: https://github.com/mozilla-b2g/gaia/pull/9486 Thank you for the effort. There is a lint error and also something needs to be clarified. Please check my comment in github.

Thanks for the quick reviews. https://github.com/mozilla-b2g/gaia/commit/d70f64b5d406f4925a8aac6fffbb983a199a3bd1

Nominate for leo+ because the patch improved the performance and also fixed a leo+ bug 856931.

On v1-train I'm seeing this error when launching the settings app on a device: E/GeckoConsole( 425): [JavaScript Error: "ReferenceError: MouseEventShim is not defined" {file: "app://settings.gaiamobile.org/js/settings.js" line: 831}] This should go away if the patch is uplifted.

Not blocking but please nominate for v1.1 uplift including a risk assessment to taking this.

Anthony, per comment 7, could you help nominate for v1.1 uplift? Thanks!

Since "Bug 879117 - [Buri][AUD] terrible to adjust ringer & alarm volume in setting" is nominated to leo+, we should uplift the patch to v1-train. I have a test for uplift process with fixing error. It works fine for me.

WFM - marking as blocker since duper didn't.

I was not able to uplift this bug to v1-train. If this bug has dependencies which are not marked in this bug, please comment on this bug. If this bug depends on patches that aren't approved for v1-train, we need to re-evaluate the approval. Otherwise, if this is just a merge conflict, you might be able to resolve it with: git checkout v1-train git cherry-pick -x d70f64b5d406f4925a8aac6fffbb983a199a3bd1 <RESOLVE MERGE CONFLICTS> git commit

Because it's a leo+ issue for blocking Bug 879117, I have helped to fix the conflict and merged for v1-train. v1-train: c9c90d0472bafa3df1649b46cfa1e188aad5c446
