Status: RESOLVED DUPLICATE of bug 848808

(Core :: DOM: Editor, defect)

Description

[Jan Kurianski]

Attachment: test.html

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31

Steps to reproduce:

Applied a CSS transform scale property of 0.7 to a contentEditable div, and clicked on the first character to edit text.  Used my keyboard arrow key to position the caret between each character and observe it flash.


Actual results:

The caret is not rendered when positioned between some characters.  The likelihood of the caret not being rendered increases when the scale is lower (e.g. at scale 0.5 the caret is less likely to appear).


Expected results:

The caret should always appear.

(For reference, other browsers display the caret with a 2px width in a gray shade whereas in Firefox it disappears.)
