Unfortunately, we can't use `handleEvent` in this case, because [the "alarm edit" panel is now formally inheriting from our `Panel` class](https://github.com/mozilla-b2g/gaia/pull/12868/files#diff-e6fd1edb60a629517130cbefe4489542R69), which [itself defines a `handleEvent` method](https://github.com/mozilla-b2g/gaia/blob/e68a11adb9e29f60043737f9d8bf81f6c5fd34e5/apps/clock/js/panel.js#L25-L38) that we cannot shadow.

...but you're right; this is a lazy name. `handleDomEvent`? Uhg, I don't know.
