522945 - Canvas text drawing fails after maxWidth is used on first text draw

Status: RESOLVED FIXED

(Core :: Graphics: Canvas2D, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: 

If the first call to fillText() on a canvas context uses maxWidth, subsequent calls to fillText will not work.

It looks like this may be a failure to correctly auto save-restore the context.  Drawing a string without maxWidth on the first call to fillText will result in this bug being avoided as far as I can tell.  If there are some cases where that is not accurate, a simple change of the fillStyle property or calling save/restore before a fillText should work.

Reproducible: Always

Changing blocking1.9.3: from alpha1 to beta1 per conversation with Joe Drew and Jeff Muizelaar.  Still good to fix sooner rather than later, though.

Moving to betaN for triage to a specific milestone

Unless this is a regression, there's no reason this needs to specifically block Firefox 4.
