290468 - Strange behaviour when highlighting text in text box

Status: RESOLVED DUPLICATE of bug 290469

(Firefox :: General, defect)

Description

[Steve England [:stevee]]

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b2) Gecko/20050415
Firefox/1.0+

1. Go to any site with a text box on the page, eg: www.google.com
2. Copy and paste this sentence into the textbox: "The quick red firefox jumps
over the lazy IE this is a long sentence that is longer than the textbox is"
3a. Click anywhere in the textbox and try and highlight some text by dragging
the mouse over it.
3b. With some text highlighted and the left mouse button kept pressed, move the
mouse all the way to the right of the screen.

Expected: Text is selected nicely
Actual: The selected text goes mad. The position and the highlighting of the
text is inconsistent. When moving the mouse out of the text box the cursor
position no longer coresponds to what text is being highlighted.

Also, whilst filing this bug (in the description textbox I am entering this text
into) trying to highlight more than one line of text sometimes goes wonky too.

Apologies for the vagueness of what is wrong, but it is hard to explain but very
easy to see.

Maybe fallout from 289792?
