Bug 13891 – REGRESSION: Taloussanomat.fi web site not rendering correctly

• Status: RESOLVED
• Resolution: FIXED
• Component: Layout and Rendering

[Marko Buuri]

Taloussanomat.fi web site not rendering correctly with webkit nighly versions. This is regression from Safari 2.0.4 (419.3) that renders the site perfectly.

Confirmed with r21802. Interestingly, the content seems to be rendered correctly at first, but then gets moved out of sight.

I'm seeing the same behavior with both Safari 2.0.4 and TOT, namely that the main content seems to be pushed down below the leftmost column (presumably because their container gets an unexpected vertical scrollbar).

Very interesting, because I am not able to reproduce this problem with this standard setup: iMac G5, OS X 10.4.9, Safari 2.0.4. The nightlies on the other hand have been rendering this site incorrectly for as long I have have used them on this same system, which is for as long as roughly few weeks.

The site uses overflow-x and overflow-y, which were not supported by Safari 2.  Now we are honoring them.   For some reason we're overflow vertically when Firefox did not, so we'll need to reduce to figure out why.

I think this is about font-size: 0 mapping to 1px (if that's still the case).

I'm pretty sure it's the font-size: 0 thing.

[Dave Hyatt]

I'm not sure it's that simple.  Setting a minimum font size of 9px in Firefox does not result in any overflow appearing.

[Dave Hyatt]

Actually never mind.  Firefox seems to special-case 0.  If a font is size 0 then the minimum font size (and zoom) do not apply, since obviously it was not intended to be displayed (makes sense).

The annoyance here of course is that AppKit can't handle zero size fonts, opting to return a font of size 12 instead.

Does the problem still occur on the live site?  I'm not sure I see anything wrong in TOT

Looks like usage of overflow-x has been commented-out in <http://www.taloussanomat.fi/css/layout.css>, which fixes the problem on the site.

IMO bug 11004 is related to this bug.
