Status: NEW

(DevTools :: Inspector: Rules, defect, P2)

Description

[Julien Wajsberg [:julienw] (PTO -> Mar 17)]

Attachment: testcase-hover.html

STR:
1. Open the testcase.
2. Open the inspector.
3. Click on the arrow to select an element.
4. Click on the "hover me" link.

Expected Result:
* The link is highlighted in the DOM tree view.
* Its normal styles are shown in the Rules panel on the right.

Result:
* The link is highlighted in the DOM tree view.
* Its hover styles are shown in the Rules panel on the right.
* But actually the normal styles are applied in the element.
* When right clicking on the element in the DOM tree view, "hover" is disabled.

Additional notes:
* selecting the element directly in the tree view works fine, as does the sequence "Right click on the element + click on Inspect Element".

Tested in latest nightly v50 (20160721030216).
Also happens at least in v49 (20160706004036) among other issues.
Adding "qawanted" to check in beta/release.


[Tracking Requested - why for this release]:
Regression, makes the inspector uneasy to use.

Inspector bug triage (filter on CLIMBING SHOES).

ni on Florin to check the other branches when they get a chance.

Comment 3

[Paul Silaghi, QA [:pauly]]

Reproducible on 48 RC, 47.0.1.
Also repro on FX 10.0.2, so it's not a recent regression.

I don't think release management needs to track this. If someone lands a fix though, we could still uplift at least to aurora.
