832514 - -moz-user-select:none text can be highlighted by drag selection, even though the text won't be copied

Status: RESOLVED DUPLICATE of bug 739396

(Core :: DOM: Selection, defect)

Description

[Chris Peterson [:cpeterson]]

This was a regression in Firefox 11. In Firefox 10, "-moz-user-select:none" text is NOT highlighted when you drag a selection over a "none" text (thought CMD+A to select all text WOULD highlight it).

Did you know the regression window more accurately than Firefox 10-11?

(It might be obvious from commit logs.)

Comment 3

[Chris Peterson [:cpeterson]]

I think this was a regression in Nightly 2011-12-21, the first 11.0a1 build. Unfortunately, nothing in the changelog jumps out at me as particularly suspicious:

hg bisect says this selection bug is a regression from bug 619273:

(The regression window I posted in comment 3 was incorrect.)

Is this a duplicate of bug 739396 ?

mats, this bug does look like the same problem as bug 739396.

btw, here is the test case (originally from bug 166235) that I used to test this bug.
