Tab isn't scoped properly in Firefox

[claydiffrient]

This may be more of a problem with my app, but tab never seems to scope right in Firefox. It doesn't start in the modal. I think that something might be happening that prevents the initial item from grabbing focus with Firefox.

Cannot reproduce this issue. I suspect it may have been fixed with #9

can you reproduce if you checkout the old code?

I tried reproducing using a commit from before the issue was logged. I still wasn't able to reproduce. It looks like #9 didn't fix this issue, but it may be something app specific that has changed for @claydiffrient. He is going to try checking out an older version of his app to see if it is reproducible on his end.
