Search bar does not load discussion notes selected labels

Summary

When you click on a discussion note label, the page changes to the issue filtered search page. Normally, it would include the selected filter but it currently does not do that.

Steps to reproduce

  1. Scroll below this issue and click on ~Frontend
  2. Notice how the new page has the filter applied but it does not show up on the search bar

Expected behavior

Filter should autopopulate on search bar

Actual behavior

Filter does not autopopulate on search bar

Possible fixes

Looks like the notes page passes the label param as label_name=Community+Contribution while the search bar only processes them when it is encoded as label_name%5B%5D=Community+Contribution
