Mouse back and forward buttons don't work in Elk client

[mediapinta]

As the title say, mouse back and forward buttons don't work in the Mastodon's client Elk. I have a regular ergonomic mouse with two buttons for back and forward. It works fine in every webpage and webapp, but in Elk it's not working at all.

I can't reproduce this bug in GNOME Web.
