1108277 - the <canvas> element returns incorrect min/pref inline-size in vertical writing modes

Status: RESOLVED FIXED

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

Description

[Jonathan Kew [:jfkthame]]

Attachment: testcase for canvas size in vertical mode

For a simple demonstration, put a <canvas> inside an html <button>, as in the attached testcase, and note how the *width* of the canvas contributes to the *height* of the enclosing button.

Attachment: part 2 - Make Get{Min,Pref}ISize in video and plugin frames aware of vertical writing mode

Looking around in layout/generic, I notice the same issue exists for video and plugin frames; let's fix those while we're here.
