Load attached test case that uses -webkit-text-size-adjust: none; 2. Cmd= and Cmd- to increase and decrease the font size. * RESULTS Does not work. This is a serious accessibility bug for low-vision or zoom users, and a usability bug for all users. * REGRESSION Regression occurred at the time text-size-adjust was implemented. * NOTES This property should prevent webkit from resizing text automatically, but it should never prevent the user from resizing the text explicitly. This is also in violation of WCAG Guideline 1.4.4 and UAAG Guideline 4.1. WCAG Guideline 1.4: http://www.w3.org/TR/WCAG/#visual-audio-contrast 1.4.4 Resize text: Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality. (Level AA) UAAG Guideline 4. Ensure user control of rendering http://www.w3.org/TR/UAAG/guidelines.html#gl-user-control-styles 4.1 Configure text scale (P1) (1) Allow global configuration of the scale of visually rendered text content. Preserve distinctions in the size of rendered text as the user increases or decreases the scale. (2) As part of satisfying provision one of this checkpoint, provide a configuration option to override rendered text sizes specified by the author or user agent defaults. 595842 1 ap 2012-04-04 13:17:46 -0700 See also: bug 56543. 595847 2 simon.fraser 2012-04-04 13:21:57 -0700 *** This bug has been marked as a duplicate of bug 56543 ***
