Task: Need to add in the verifyGenericRolesBySelector() call missing from a few files

[cookiecrook]

If #109 doesn't land, we need to add in the verifyGenericRolesBySelector() call missing from a few files: tab-roles.html and list-roles.html.... (see diff in web-platform-tests/wpt/pull/45032 but wait for a decision on #109 to avoid potential conflict.)

Besides tab-roles.html and list-roles.html, I think we're also missing the .ex-generic check in menu-roles.html (see these tests). Looks like it's five total tests across these files that are checked in but not running.

I'm happy to do this when I get a chance, on resolution of #109.

r+ on #109 btw. thanks.
