Remove link removes all filters

I've tested this merge request on a view that had single value and multi-value filters, with no Ajax, core Ajax and Ajax with Views Ajax History. It resolved the issues for me.

In my testing of this patch, clicking on the "x" for one of the filters caused the page to reload and the other filter values were lost in the reload.

In my use case the view is added to the page in the page template via lazy views.

Tested the fixes from the MR. They didn't work for me. The page was just reloaded.
I've found that for multiple value filter the search arguments can have such structure:
?geography_type[region]=region&geography_type[country]=country
So I've added such lines:

          // Remove keyed element.
          url.searchParams.delete(`${selector}[${value}]`);

It helped to fix the remove links I tested.
Attaching the patch.

It looks like neither of the previous patches are applying cleanly to version 2.0.0-alpha3 that was just released this week.

I have re-rolled the patch for 2.0.0-alpha3

Patch from #8 applied and solved the issue for us on a view without AJAX (2.0.0-alpha3).

Confirming patch #8 works on a view without AJAX.

The original merge request has been updated to include the latest changes from #8 it also reintroduces support for multi-value filters that are formatted as ?filtername[]=foo&filtername[]=bar. This was removed in patch #6. It seems multi-value filters can have different formats in the url search params.
