Nice! I'm hoping to get a release candidate out for 4.0.5 soon.

@julianyus it looks like the last two assertions in select-tests are failing for me in Firefox:

Seems like normalizedItem3.id and normalizedItem3.text are returning objects, not scalars.

@alexweissman
To me it works in firefox.
Did you do "grunt compile"? I did not include the compiled files (dist folder) in the commit.

Did you do "grunt compile"?

d'oh! Thanks, I always forget that the tests are pulling from dist/ ☹️

Ok this looks good, I'll put it out in the RC.
