605028 - incorrect intrinsic width calculation when collapsable space follows preserved line break

Status: NEW

(Core :: Layout: Block and Inline, defect)

Description

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

We incorrectly compute intrinsic width in the following testcase (but do the layout correctly):
http://test.csswg.org/suites/css2.1/20101001/html4/white-space-mixed-003.htm
http://test.csswg.org/suites/css2.1/20101001/xhtml1/white-space-mixed-003.xht

In the first test, we don't collapse away the whitespace at the beginning of the second line when we're doing intrinsic width calculation (but we do when doing layout).
