Michael and Alexey, this bug is in the dependencies list of bug 300030 so it won't be forgotten. If you go to bug 300030 you can see it there :)

Attachment: minimized testcase

Minimized testcase:
an abs-pos block containing
  a floated block
  a block containing
    a floated block

In firefox 2, the floated blocks are next to each other. Post-reflow-branch, they're not.

Comment 6

[dolphinling]

A quick scan for duplicates showed none, though many reflow-branch regressions have non-descriptive names.

We match Safari on attachment 302539 [details].  Does Safari behave the same on the site as well?

Can you explain why this rendering is (or could be) correct? I must be missing something, but shouldn't the preferred width be the sum of the float preferred widths?

Comment 9

[dolphinling]

Roc, you marked this P1 and blocking-. Was that supposed to be blocking+ ?

[Robert O'Callahan (:roc) (email my personal email if necessary)]

No. We're marking this WONTFIX. If we chose to reopen it, it would be P1.

The reasoning is that when we compute the preferred size of the abs-pos element, we don't know which floats will be next to each other, so we have to guess. We use the same heuristic that Safari uses, which is that if the floats are in the same block they could be next to each other. So in this case we guess they should not be next to each other.
