 * that rewrite their URL (e.g. Electron/desktop builds, or `$current_url` rewrites in
 * `before_send`) can make targeting match the logical URL instead of the raw browser URL.

 *
 * Called on every rrweb event by the replay URL triggers/blocklist, so a configured
 * `get_current_url` override should stay cheap.
