Adding a facet search to a menu leads to fatal errors.

Problem/Motivation

I'm Trying to add a menu link to a pre-selected facet page, but it is throwing a fatal for the route parameters being too long

Drupal\Core\Entity\EntityStorageException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'route_param_key' at row 1

The param key is full of empty values:
f0=&f1=&f2=&f3=&f4=&f5=&f6=&f7=&f8=&f9=&f10=&f11=&f12=&f13=&f14=&f15=&f16=&f17=&f18=&f19=&f20=&f21=&f22=&f23=&f24=&f25=&f26=&f27=&f28=&f29=&f30=&f31=&f32=&f33=&f34=&f35=&f36=&f37=&f38=&f39=&facets_query=category/frames-5734/riding-type/dirt_jump_slopestyle

This looks to be the way it's allowing facet pretty paths to work in the first place?

FacetsRequestTrait:

  public function pushRequest(RequestStack $request_stack, $route_title, $filters) {
    // We need to use a dummy, albeit existing route (in this case system.admin)
    // so that Url objects can be built for this route. Otherwise, calls to Url
    // will not work as the route does not exist.
    $route = new Route('admin/{facets_query}/{f0}/{f1}/{f2}/{f3}/{f4}/{f5}/{f6}/{f7}/{f8}/{f9}/{f10}/{f11}/{f12}/{f13}/{f14}/{f15}/{f16}/{f17}/{f18}/{f19}/{f20}/{f21}/{f22}/{f23}/{f24}/{f25}/{f26}/{f27}/{f28}/{f29}/{f30}/{f31}/{f32}/{f33}/{f34}/{f35}/{f36}/{f37}/{f38}');
    $route->setDefault('_title', $route_title);
    $route->setRequirement('facets_query', '.*');
    $route->setDefault('facets_query', '');

There has to be a better way here?
