Starting with Chrome 33, certain types of input elements do not
support the selection API (in fact, they throw when you try to
access the property). This prevents us from fully simulating typing
in the atoms.

Try to case these cases and throw a more descriptive error, pointing
the user at https://code.google.com/p/chromium/issues/detail?id=330456
so they have the proper context for why typing no longer works as
expected.
