            Bug ID: 22803
           Summary: Browser manufacturers request clarifying text for
                    drawSystemFocusRing functions
    Classification: Unclassified
           Product: HTML WG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CR HTML Canvas 2D Context

During implementation, Google pointed out that it was not clear how styling
could be determined that would allow user agents to determine the style applied
to the system focus ring and asked that a clarifying note be included. This is
text has been shared with the major browser manufacturers and my colleague at
Google approved the text and this is being shared with the other browser

The following change needs to be made to the Canvas 2D API for clarification.
It is a Note and does not impact CR. It should either come at the end of step 2
in the drawSystemFocusRing(element) processing or as a note following the
definition of drawSystemFocusRing(element) and drawSystemFocusRing(path,

Note: User agents may use the <a
href="http://www.w3.org/TR/CSS2/ui.html#dynamic-outlines">CSS outlines around
focused elements</a> in determining the system focus style on fallback elements
to determine the standard system focus ring style drawn on the canvas. This
would mean that if an author were to override this style that the appearance of
the standard focus ring drawn on the canvas could reflect this change in style.
