Perhaps the gutenberg_add_edit_link_filters isn't set up in Core? cc. @pento

Ah, I skipped merging that function, I missed that it handled the wp_block actions as well as the "Edit in the classic editor" action on other post types.

I've moved this to Trac since it's a bug in Core and not the plugin:
