Repro steps to trigger CORB:

  1. Make sure that CORB is active
  2. Open Javascript console (e.g. by pressing Ctrl-Shift-I in Chrome).
  3. Press the button below to add an <img src=""> element that tries to sneak a cross-origin text/html document into memory of a renderer process hosting another origin.
  4. Observe that CORB blocks the http request triggered by the inserted img element.
