Hmm, ToSupports() should be removed completely by one of the following patch for follow up bug.

Ah, but if those methods are useful if there are some overloads, ignore these comments.

Although, I'm not familiar with sandbox and xpconnect. But the changes must be okay since you must be familiar with them.

Ah, could you please move "," to below ":"?

Comment 20

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

I wonder, it might be better to notify other developers of removing nsIDOMEvent with "Intent to unship" mail.

Comment 21

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

bz: When you replaces nsIDOMElement with dom::Element, could you let me know? Currently, editor has overloads of such for avoiding  using virtual method calls as far as possible. I don't want to merge them and don't want to increase virtual calls. (Although, I'm renaming a lot of non-virtual methods of editor in bug 1451672.)

Fixed.

Actually, looks like bug 1452981 removed it and ToCanonicalSupports from Even this morning.  ;)

> Cannot compare Event::GetOriginalTarget() and commandElt directly now?

You're right, we can.  Fixed, like so:

            NS_ENSURE_STATE(event->GetOriginalTarget() != commandElt);

> nit: Cannot make this nsAutoString?

Can, and done, for all three callsites.

> Although, I'm not familiar with sandbox and xpconnect.

Not a problem.  I asked kmag to review this part and he said r+ on IRC.

> Ah, could you please move "," to below ":"?

Done.

> I wonder, it might be better to notify other developers of removing nsIDOMEvent with "Intent to unship"

I can do that.

> bz: When you replaces nsIDOMElement with dom::Element, could you let me know?

Yes.  Bug 1455674 filed to track that.
