601233 - Setting canvas context2d.font property to an invalid font style makes fillText() inherit font settings from CSS

Status: RESOLVED DUPLICATE of bug 508452

(Core :: Graphics: Canvas2D, defect)

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0b7pre) Gecko/20101001 Firefox-4.0/4.0b7pre
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.11pre) Gecko/20100928 Ubuntu/10.04 (lucid) Firefox/3.6.11pre

See URL (I'll also attach it here as a test case); I set the context 2D "font" property to a blank string (e.g. an invalid font style) on one canvas, and fillText() uses the font style inherited from CSS.  The second canvas is rendered with the default font "10px Serif", because the font property is not touched.

I'm only seeing this behavior on Firefox 3.6 branch (Mozilla 1.9.2).  On Firefox 4.0 beta7-pre, I get the expected behavior: Both canvases are rendered exactly the same with the default font.

Reproducible: Always

Right, because we fixed this since 1.9.2...
