Reproduce the problem in Chrome with a custom instance address, access key, and one local reader enabled. Start from the extension-page console stack, especially RSSItem-DD8R1cdP.js and icon-DjeKhcls.js, then trace the error back to its source. Done means clicking the extension icon renders normally without the TypeError.
