This change adds computation of ARIA roles for a number of SVG elements
for which, if the element meets the SVG spec criteria for inclusion in
the accessibility tree, the computed ARIA role should be
“graphics-symbol”, and should otherwise be “generic”.
This change also adds similar role computation for the SVG foreignObject
element (the role for which, if the element meets the SVG spec criteria
for inclusion in the accessibility tree, should be “group”, and should
otherwise be “generic”).
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
This change adds support for computing accessible names for SVG
elements, per the https://w3c.github.io/svg-aam/#mapping_additional_nd
spec requirements. Otherwise, without this change, accessible names for
SVG elements don’t get exposed as expected.
