Exposed form on view mode page sets action is base page URL

I am using an exposed filter on a view within layout builder in a view mode page. The action parameter on the form element of the exposed filter is the base page, rather than the view mode page. This causes the form submission to fail.

I'm finding that the cause is at least partly that the current route match is the base page rather than the view mode page - it seems that the module doesn't provide additional routes for the individual pages.

Does that sound right?
