Use ConstructBlock when creating scrolled and absolutely positioned blocks. Removes copied code and makes columns work in such situations. bug can be seen here http://inopressa.ru/jpost/2005/03/08/11:27:14/Goussinsky and in the attached testcases.

testcase with english text, containing div defines height and total width, contained divs are containing the same text, with different negative offsets, so 1st div is first column showing 1st part of text 2nd has negativ offset skipping the part of text displayed by the first, and is positioned to the right, so it should display part of the text following the first part. Accordingly 3rd div should skip the parts shown and shoiw the next part of the text. In the real page there is JS to scroll through longer texts. I´ve put a black dashed border around the containing div, and coloured borders around the contained divs. I´ll attach screenshots from before and after the regression.

I just noticed that the testcase downloaded from bugzilla rendered differently, so I´ll attach screenshot. Remote I´ve only checked the original URL working with 20050207, and failing 20050208. I checked the working of this testcase only locally, and the failing also remote. Maybe bug 285309 is related.

Boris, this bug seems to be related to the fix of Bug 277420 Setting overflow disables column layout [columns] I suspect it is working now as intended, but I´m always eager looking at bugs declared 'ìnvalid' to improve my knowledge. See comment 4 for regression date and direct link to the russian language page showing the regression. see comment 5 for my own testcase from what I understand could be the problem. Attachments include testcase and screenshots.

This is probably a duplicate of bug 282754. Marking dependent for now.
