test case

AX: WebKit does not expose text alternative of CSS generated image content. E.g.

  a[href$=".pdf"]::after { content: url(./pdf.png), "(PDF)"; }

Note: I think it should retain the AXImage's AXRole and AXRoleDescription, but otherwise let AT decide what to speak. Since this is inside a link, it should not be treated differently than if there was a hardcoded markup image in the link. So, on the link you'd hear "link, User Guide (PDF)" and if it was just plain text, you'd hear two elements, "User Guide" static text and then "(PDF) image"

Once this is patched, you should include a test to ensure it does not regress -webkit-alt.

content: url(resources/cake.png), "foo";
-webkit-alt: "bar, not foo";

content: url(resources/cake.png), "";
-webkit-alt: "not empty";

content: url(resources/cake.png), "foo";
-webkit-alt: ""; // should be empty, not foo
