let is_error = ty == &atom!("error") && self.is::<Window>();

Thanks to the is::<Window> checking (☝️); we've handled the sourceText correctly but Servo currently doesn't pass the new test due to missing on prefix for the function name.

Prefix `on` for function name of inline events

While checking what needs to be done for the spec-update, I've noticed the logic of checking `is window-reflecting element (e.g. body and frameset)` is already handled by the `is` casting function.

However, we still failed to pass the tests because we're missing `on` prefix for inline functions.

I'm not sure if this patch is good enough (or maybe at least I need to add a comment for why adding `on` prefix?).

Besides, I checked [how Gecko handles](https://searchfox.org/mozilla-central/rev/8bc4e35c9bb47c1fe3131e6155d9f482e1efef9a/dom/events/EventListenerManager.cpp#1012-1022) and looks like they also just pass the atom directly.
But, the [generated atom](https://searchfox.org/mozilla-central/source/__GENERATED__/xpcom/ds/nsGkAtomList.h#775) is prefixed with `on` which is correct to just pass it into the `CompileFunction`.
