1138353 - vertical-align with a <length> or <percentage> should use line-relative coordinate directions

Status: RESOLVED FIXED

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

Description

[Jonathan Kew [:jfkthame]]

Attachment: testcase for vertical-align in different writing modes

When line-relative and flow-relative coordinate systems don't match (i.e. in vertical-lr mode, typically; text-orientation:sideways-left will eventually affect this too), explicit lengths or percentage values used with vertical-align get applied in the wrong direction.

See testcase, where the 10px and -10px cases are offset in the wrong direction in the vertical-lr example.
