When rendering facets on non search page, it throws error instead of 404 on 404 pages

Problem

Add a facet block on a non search page and check the box to show facets even when source is not rendered. It works fine but when a route does not exist or is not found it throws error instead of showing the 404 pages.
The error:
Symfony\Component\Routing\Exception\ResourceNotFoundException: No routes found for "/sdfsdf". in Drupal\Core\Routing\Router->matchRequest() (line 124 of core/lib/Drupal/Core/Routing/Router.php).

Steps to reproduce

Add a facet block to page or render programmatically.
Make sure facet can be rendered without facet source.
Go to random non-existent page which should return 404 page not found.
You will see error.

Proposed resolution

Use Url::fromRoute(''); instead of Url::createFromRequest($request); to get current url object.
