Open Browser Toolbox (Ctrl+Alt+Shift+I) 4. Type "identity-box" in inspector-searchbox, then hit [Enter] key (inspector-searchlabel is 1 of 3) 5. Check focusing node in markup 6. Hit [Enter] key again in inspector-searchbox Actual results: After step 6, Inspector does not focus 2 of 3 and 3 of 3 node. After using "Expand All", invisible node appears.

Hi Patrick, would like to confirm with you if this bug should belong to the Track #2 team. Thanks.

It's apparently a regression from bug 1264907 which had been added to the track 2 backlog only because it had to be done before the breadcrumbs could be rewritten as HTML. I don't think it should have been added to the project in the first place, but maybe that helped planning. In any case, I don't think this one should be added to the track 2 backlog. It doesn't have anything in common with the de-XUL-ification project.

Thanks Patrick.

Triaging as P3 based on the fact that this seems browser-toolbox related only. If it occurs in the "normal" tab toolbox too, then we should re-evaluate.
