1) The vertical scrollbars should not be visible (see frameset definition) 2) Extra disabled vertical scrollbars appear when you click on the disclosure triangles. No problems with Safari 2.0.2

Confirmed with a local debug build of WebKit r25814 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218). Safari 2.0.4 (419.3) with its original WebKit on 10.4.10 does not show the unneeded horizontal scroll bars.

Probably <http://trac.webkit.org/projects/webkit/changeset/14953>, which added overflow-{x,y} support.

I tested this issue using today nightly r29907 and compared results with Opera and Firefox and I can't confirm this bug. Is this already fixed?

Chasen, your test case works as expected. According http://www.w3.org/TR/css3-box/#overflow-x : "scroll This value indicates that the content is clipped and that if the user agent uses a scrolling mechanism that is visible on the screen (such as a scroll bar or a panner), that mechanism should be displayed for a box whether or not any of its content is clipped. This avoids any problem with scrollbars appearing and disappearing in a dynamic environment." So the horizontal scrollbar should be always visible in this case. If you want to get a behavior you described you should set overflow-x to "auto" instead of "scroll". The bug is INVALID.

Thanks Robert. One day I'll be able to commit. Next time I'll leave a comment when I know that the bug report is invalid.
