<div>This table shows unicode-bidi: isolate behavior (in red) with display: inline-block behavior overlapping in green.  You should see no red in this test!  Behavior between these two methods should be identical for non-wrapping strings, assuming unicode-bidi: isolate is implemented and functioning correctly.</div>
