bug#34870: 26.1; --with-xwidgets not supported if Emacs build with Motif

[Vladimir Nikishkin]

I would like to use xwidget-webkit-browse-url like described in the
Emacs manual node 31.12.2, but Emacs compiled with Motif cannot use
them.  Is it possible to do something about it?

I believe, a Motif-based webkit(or mozilla gecko?) module doesn't
 exist, although if it existed, perhaps it would make more sense
 to use it rather than a gtk widget. (If a motif-based widget
 exists, I wonder if a patch implementing it would be
 accepted if contributed?)
