1103388 - MakeSpaceTextRun should map "mixed" orientation to sideways rather than upright

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Jonathan Kew [:jfkthame]]

Attachment: testcase for various individual space runs

MakeSpaceTextRun treats a <space> with text-orientation:mixed as vertical-upright when constructing the run, which is wrong (per UTR50) and leads to unwanted results; see attached testcase.

Attachment: Use sideways orientation for lone <space> when text-orientation is mixed.

This corresponds to what UTR50 expects, as well as simply looking better. :)
