Hi Mike, should we also set this bug as [qf:p3] because of the [reserve-photon-performance]? Thanks!

Hmm, this is the undoCloseTab action, I guess we could have triaged it in the photon-perf-tabs bucket. I'll let Mike decide :-).

Thank you Florian :) I checked this with Kanru and Evelyn, Evelyn said you triaged a long long list and made this bug [reserve-photon-performance], so I'd like to confirm the [qf:p1] part  :)

Yeah, I think marking this down to qf:p3 makes sense.

This no longer causes a reflow since bug 1369140 landed.
