I don't know if FrameId is related to an <iframe>, and whether each Page has 1 implicit "frame". But, playwright seems to treat frameId and targetId as interchangeable, and chrome seems to agree (at leas to some degree); chrome will return a targetId and reuse that value for the frameId. So the simplest solution is just to remove our concept of a frameId and use targetId exclusively. This doesn't seem to cause any issues with puppeteer.
