1176509 - Selection of text is offset and incorrect

Status: NEW

(Core :: DOM: Selection, defect)

Description

[Ray Satiro]

Attachment: Selection of text is offset.gif

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20150618030206

Steps to reproduce:

Go to http://www.mediafire.com/developers/core_api/1.3/upload/
In the code window attempt to select some code.


Actual results:

Tested ESR31, Aurora, Nightly: The selection of text is offset and is not what I tried to select. The text should start to select at the location of the mouse pointer but instead starts lines below. I have attached an animated GIF that shows the problem.


Expected results:

The text I select is what should be selected of course. Google Chrome also has some problem with selecting the text in that code box but is more accurate. I could not get the page to load in IE.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
