Perfherder has detected a browsertime performance regression from push 71bf1129a12562d0be35a5df2f452fbf3c042fac. As author of one of the patches included in that push, we need your help to address this regression.

Details of the alert can be found in the alert summary, including links to graphs and comparisons for each of the affected tests. Please follow our guide to handling regression bugs and let us know your plans within 3 business days, or the patch(es) may be backed out in accordance with our regression policy.

If you need the profiling jobs you can trigger them yourself from treeherder job view or ask a sheriff to do that for you.

You can run these tests on try with ./mach try perf --alert 1706

For more information on performance sheriffing please see our FAQ.

This is merely a return to the actual performance level due to me backing out an experimental patch. This does not represent a real regression.
