The mouse events aren't meant to be fired directly by individual controls,
they're fired automatically.

Even if you did fire these events, we're currently only using them for
the Select-to-speak feature on Chrome OS, not for ChromeVox.

Normally the SELECTION event should be fired on the specific item that was
selected within a list, not on the overall container itself.
