242998 - visibility:collapse causes incorrect overflow area to be reported

Status: NEW

(Core :: Layout: Tables, defect)

Description

[Bernd]

see http://bugzilla.mozilla.org/show_bug.cgi?id=242253#c11
we should recalculate the table rowgroup row cell overflow areas when we
collapse rows rowgroups cols and colgroups. The views should be adjusted too.
The questionable cell moving should be investigated.

Attachment: collapse overflow testcase

I *think* that this is a testcase for this bug. It's not clear to me from bug 242253 what the correct behavior actually is here: clipping row1col1, or reflowing so that row 1 gets a bigger height when row 2 is collapsed.

I would really like *some* way of avoiding the clipping and getting reflow behavior, even if it's a CSS switch which causes things to be more expensive. I'm trying to construct a treeview-type widget inside of tables, and the current bug makes it difficult.
