1205426 - Computed Panel on Element Inspector Malfunctioning

Status: RESOLVED WORKSFORME

(DevTools :: Inspector, defect)

Description

[Rob]

Attachment: View of rules repeating over and over

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150826023504

Steps to reproduce:

Resizing window, selecting elements that are children of already inspected elements, just pretty much most types of behavior one would carry out while developing a site.


Actual results:

Rules in computed panel show up multiple times (ie height may show "100% 50% 100% 50% 100% 50% 100% 50% 100% 50% 100% 50% " rather than just "100%" with 50% in strikeout. Also seeing rules of parents/children/unrelated elements at times that should not be present and have no impact on inspected element.


Expected results:

Up until about a month ago this was much tidier, and not broken. If for example an element had one general CSS rule and one additional contained within a media query, the computed panel would display both rules once when the rule is expanded – the inactive one would have a strikeout. They now repeat over and over indefinitely if the window is resized to trigger each CSS rule interchangeably. I've tested this in both OS X 10.9.5 and 10.10.4, both Macbook Pros.

It would be really helpful to have steps to reproduce this.
I've been trying for a while but haven't made it happen yet.

Thanks Tom, I don't actually see the behavior anymore on the latest update (42.0), will update if it re-occurs.
