932784 - Pseudoelement disregarding parent positioning context when parent is display: table-cell

Status: VERIFIED DUPLICATE of bug 35168

(Core :: CSS Parsing and Computation, defect)

Description

[filip]

Attachment: pseudoelement_table_bug.html

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36

Steps to reproduce:

I used an :after pseudoelement inside a relatively positioned table-cell parent and positioned it absolutely.


Actual results:

The pseudoelement isn't positioned in the context of it's relative parent, but in the context of the next closest element that isn't display: table-cell.


Expected results:

The pseudoelement should be positioned in the context of it's relative parent (table-cell).

I didn't look at the testcase too closely, but I'm betting the problem is just that relative positioning of table cells doesn't work yet. (bug 35168)  Duping to that bug, since this should presumably work once that's fixed.

Yep.

Note that per spec using "position: relative" on a table cell has undefined behavior...

Incidentally, it's bug 63895 that deals with the issue of position:relative table elements being an abspos containing block, as opposed to that of position:relative actually moving table elements.
