They felt this text to be under specified: "When a canvas element represents embedded content, the user can still focus descendants of the canvas element (in the fallback content). This allows authors to make an interactive canvas keyboard-focusable: authors should have a one-to-one mapping of interactive regions to focusable elements in the fallback content." They felt this left it unclear as to how fallback content should respond to keyboard input. The suggested adding the following text "Elements in canvas fallback content should behave as if they were on the page but invisible and having no effect on layout. Mouse input would go directly to the canvas because the children do not layout so they have no position to hit test." 46541 1 cooper 2011-03-08 16:20:36 +0000 Bug triage sub-team adding a11ytf keyword because this is related to active HTML A11Y TF activity on canvas. 48158 2 ian 2011-05-06 00:53:06 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
