616334 - implement float rules 3 and 7 correctly for floats not intersecting containing block

Status: NEW

(Core :: Layout: Floats, defect)

Description

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

We currently fail four reftests in layout/floats/ that Microsoft says they've fixed and haven't gotten compatibility problems as a result of fixing.

So after Firefox 4 we should try fixing them.

They're layout/reftests/floats/...:
other-float-outside-rule-3-left-2.html
other-float-outside-rule-3-right-2.html
other-float-outside-rule-7-left.html
other-float-outside-rule-7-right.html

and in the CSS 2.1 test suite they are:

It looks to me like IE fixed rule 3 but not rule 7... though the IE I'm testing isn't the latest.

Also, the tests in http://dbaron.org/css/test/2009/float-outside-tests/ are easier to check visually.

(And IE fixed rule 5.  And they fixed the BFC displacement for one side but not the other!)
