Maybe it's not worth the trouble, indeed.

The issue at hand was presumably that the buffer's mode (i.e. eww-mode)
is not meant as a "normal entry point".  So it's more normal to have to
keep the name of the handler stable, since that is an explicit entry point.

But this handler *is* a normal entry point.
