Shouldn't this be the id of the element, not the name?

You should add cvox.ChromeVoxUserCommands to the closure dependency list and
make sure all tests that currently set that list append to it (or move the
utility to the test that needs it).

This also has an undeclared dependency, but I'd just get rid of this overly
trivial function.

[dmazzoni, 2014/09/23 18:02:41]

It's useful for chaining and will make porting other tests easier, so I'd prefer
to leave it and fix the dependency.
