307102 - width of abs pos replaced elements not intrinsic when left:0;right:0

Status: RESOLVED FIXED

(Core :: Layout: Positioned, defect)

Description

[Hixie (not reading bugmail)]

According to 10.3.8:1, the used value of 'width' for absolutely positioned,
replaced elements is determined as for inline replaced elements. However, we
seem to be letting left:0;right:0 override this.

Erm... so for a replaced abs pos element there's no way to get the left:0, right:0 behavior?  Why not?  That is, what is the point of the first rule in section 10.3.8?  If the author wanted that behavior he would have used auto for left or right, no?

I sent mail to www-style about this...

I guess if we decided to fix this we'd need to change the nsHTMLReflowState logic to discard right or left for replaced elements depending on direction...
