Only run tests for the non-applicability of the selection API for supported types.
 
There's little point in running these tests; they should all fail, because
browsers will fall back to the 'text' type, which does support the API.

I didn't make the test fail if one of the types is not supported; there's
already a number of tests for that, and it isn't really the point of this one.
