1021040 - Rules headers duplicated intermittently

Status: RESOLVED DUPLICATE of bug 1017115

(DevTools :: Inspector, defect)

Description

[J. Ryan Stinnett [:jryans] (Use needinfo, replies may be slow)]

STR:

1. Go to http://www.coingecko.com/
2. Right-click -> Inspect Element on the market cap of Bitcoin (span.currency-exchangable)

ER:

The rules tab looks normal (https://cloudup.com/cmQduW8cH0X).

AR:

Many of the section headers are duplicated at the top of the rules tab (https://cloudup.com/cv7IfMvXE5G).

I am using the toolbox docked to the bottom of the window.  This page appears to mutate the main table element (#gecko-table) when the toolbox is resized vertically.  The rules tab then rebuilds itself.  Sometimes the headers are duplicated, and other times they aren't.  Try resizing the toolbox vertically to see the issue go away, come back, etc.
