9691 - {css2}visibility: collapse == hidden (except certain table elements)

Status: VERIFIED DUPLICATE of bug 21701

(Core :: CSS Parsing and Computation, defect, P3)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Tested on: mozilla.org, 1999-07-10-08-M8, Linux.

The property visibility: collapse should be treated the same way as hidden, not
as visible.  Collapse is only different from hidden if display is table-row,
table-column, table-{header,footer,row}-group, or table-column-group.

See http://www.w3.org/TR/REC-CSS2/visufx.html#visibility .

I believe you said you'd take care of the frame painting issues on this one. The
views should be doing this correctly now...

This should probably be marked a duplicate of bug 21701, I think.

Yup, looks that way to me, too

I'm verify that this bug is a duplicate of 21701.  Bug 21701 is about the misuse
of hidden, visible and collapse with the Mozilla source code.

Migrating from {css2} to css2 keyword. The {css1}, {css2}, {css3} and {css-moz}
radars should now be considered deprecated in favour of keywords.
I am *really* sorry about the spam...
