13481 - {css1} clear collapses margins!

Status: VERIFIED FIXED

(Core :: Layout, defect, P3)

Description

[Hixie (not reading bugmail)]

Giving a block a non-none value for the 'clear' property makes that element
appear directly under the previous element (or previous float, whichever is
lowest). It ignores any margins on previous siblings and itself.

For example:

   <p style="margin: 30px"> Hello </p>
   <p style="clear: both">  World </p>

...renders without the vertical whitespace expected (30px).

David: I cc'ed you again as you seem to be the reporter of all the other 'clear'
related bugs and therefore I assume you are very interested in this issue...

Fixed with a checkin earlier today. I was clobbering one of my "applyTopMargin"
flags inappropriately (in this case exactly: when the child block element had
clear style!).

Using 9/28 Apprunner, verified bug fixed.

Migrating from {css1} to css1 keyword. The {css1}, {css2}, {css3} and {css-moz}
radars should now be considered deprecated in favour of keywords.
I am *really* sorry about the spam...
