Links to entity URIs with special characters in query parameter names are broken, especially since Drupal core 7.55

How to reproduce:
* Configure term paths like "browse?f[0]=category:[tid]"
* Have a term view listing linked terms

Before core update, good:
* Link is like "example.com/browse?f%5B0%5D=category%3a123"
After core update, bad (note double encoding):
* Link is like "example.com/browse?f%255B0%255D=category%3a123"

How to fix:
* (proposed:) #2909714: drupal_get_query_array() does not urldecode query names
* Alternatively, make some ugly workarounds here

Background: In \views_handler_field::render_as_link a query is first built then parsed. Since 7.55 special characters are encoded, but not back decoded, so in the absence of tokens this is not an identity transformation anymore.

    // If the query and fragment were programatically assigned overwrite any
    // parsed values.
    if (isset($alter['query'])) {
      // Convert the query to a string, perform token replacement, and then
      // convert back to an array form for l().
      $options['query'] = drupal_http_build_query($alter['query']);
      $options['query'] = strtr($options['query'], $tokens);
      $options['query'] = drupal_get_query_array($options['query']);
    }

Note: First i thought i can reproduce this with any linked text field, but i did not manage to.
