380066 - Text gets drawn above other box, while its background gets drawn under it

Status: RESOLVED INVALID

(Core :: Web Painting, defect)

Description

Attachment: testcase

See testcase, I would not expect to see the text, but I'm still seeing it with current trunk build. I'm also seeing it with current branch builds.

Or maybe I'm completely misunderstanding the concept of stacking contexts and stacking levels?

This testcase is the same as the first, but without using float:left.

I think we're correct for the first testcase. Floats are supposed to paint in front of in-flow block backgrounds (step 4 and 5 of zindex.html), and in-flow inlines paint in front of floats (steps 5 and 7 of zindex.html).

I think we're also correct for the second testcase.

You're right, thanks for the explanation.
