388026 - whitespace at the right of right-aligned block causes parent block to scroll

Status: VERIFIED FIXED

(Core :: Layout: Text and Fonts, defect, P2)

Description

[Robert Kaiser]

Attachment: testcase

On many of my pages, I'm using a right-aligned footer block (<div>).
On trunk, I found that some of them made the main content div, which has overflow:auto set, display a scrollbar though they never did that before (i.e. on branch or older builds).

I could reduce the difference between pages that show this error to a space at the right side of the right-aligned text.

See the attached testcase for a working and a non-working case, which only differ by this one space. I don't think we ever should display a scrollbar there...

Seeing this on OS X width Camino trunk and Minefield.
And no there shouldn't be any scrollbar.

--> makes it a regression from bug 367177.

Ok, I see it at http://www.shoutcast.com/ where I see a horizontal scrollbar in current trunk builds. This is a testcase based on that site.

Attachment: test case with text-align center

When resizing the window to the length of the text string, this triggers a horizontal scrollbar.
After the text, there is a line-break in the source-code.
