411374 - Inconsistent placement of absolutely-positioned div with {ib}, border

Status: NEW

(Core :: Layout: Positioned, defect)

Description

[Jesse Ruderman]

The three attachments have identical final DOMs, but the red square appears in three different places.

static:       below the M, on the left
dynamic-text: covering the top-left of the M
bounce:       covering the top-middle of the M

Depends on what you mean by "correct", but the static rendering is what we aim to produce.

Comment 7

[Boris Zbarsky [:bzbarsky]]

Wasn't there another bug along these lines that you filed recently? This looks like the same issue.

Comment 8

[Jesse Ruderman]

Bug 409065?  The testcases don't look very similar to me.

Yeah, that one.  I'm not saying they definitely are, just that I suspect that they are likely to be (based on the code flow, not the testcases).
