nsIHTMLEditor.setDocumentTitle() is used only by Thunderbird, Mail and
Composer of SeaMonkey. Additionally, they can set editable document
title with |document.title = "foo";|.
The only difference of a call of |nsIHTMLEditor.setDocumentTitle()| and
|document.title = "foo";| is, nsIHTMLEditor.setDocumentTitle() makes the
change undoable.
However, only for the method, we need to maintain
mozilla::SetDocumentTitleTransaction class. Of course, I don't want to
do that without some good reasons.
As I explained in bug 1312989 comment 0, I don't think that undoable
document title change doesn't make sense for users. Therefore, I suggest
to remove supporting undoable document title change in bug 1312989 and
nsIHTMLEditor.setDocumentTitle() itself in bug 1312991.

Note that I don't want to do them in 52 because 52 will be the next ESR.
So, I'd like to do them in 53.
