342335 - Cairo - Text selection highlight incorrect length after period and two spaces in line

Status: RESOLVED DUPLICATE of bug 340255

(Firefox :: General, defect)

Description

[Barry Marshall]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060619 Minefield/3.0a1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060619 Minefield/3.0a1

With Minefield, if you select text on a line in this page, if the sentence has a period followed by spaces, the calculation of where to stop drawing the text selection highlight goes off and will be drawn as if it is partially selecting the next character.

This can be a problem for words like "Aspell", since the l can fall within this overshoot area and the user will think that this is selected, when it isn't.

Note that the problem seems to be specific to this page, since the problem does not seem to occur on the Bugzilla entry page.

This does not happen with Firefox 1.5.0.4.

Reproducible: Always

Steps to Reproduce:
1.Start Minefield
2.Load webpage
3.Place mouse cursor at the start of the line "LGPL for English only, I think. From what I'm told, we'd really like to use ASpell,"
4.Hold left button down and slowly begin to select text in the line.

Actual Results:  
When you reach the AS in ASpell, the highlight will mark the left-hand edge of the p.

Expected Results:  
The p should not be marked.

Pictures to be attached.
