• #12869 ade0aed Thanks @emily-shen! - Local explorer: validate host and origin headers before Miniflare modifies them

  If routes are set, Miniflare will alter the host and origin headers to match, causing the local explorer to mistakenly identify and block same-origin requests.

  Note the local explorer is a WIP experimental feature.
