398820 - Percentage padding-top does not respond to dynamic changes in page width

Status: NEW

(Core :: Layout, defect)

Description

[Jesse Ruderman]

Gecko doesn't update the padding amount when padding-top is specified as a percentage and the page's width changes.  (It's a percentage of the page's width rather than the page's height as specified in http://www.w3.org/TR/CSS21/box.html#padding-properties.)

Attachment: Testcase to illustrate resize rendering.

If a percentage padding is specified in a block-level element, inline elements it contains are not positioned properly after window is resized.

Resize window to see how padding-top does NOT change.

Comment 5

padding-top does not change in a block level element if it's specified as a percentage and both padding-left and padding-right as non-percentage and the element has either float or position absolute/fixed.
