Re: [w3ctag/design-reviews] Web Authentication: Large Blob extension (Issue #820)

@nsatragno + others, thanks for your developments on this! 

unfortunately I'm finding that Chrome (ver 117.0.5938.88) is NOT able to save a largeBlob in [the glitch demo](https://glitch.com/~webauthn-large-blob), but Safari 17 (desktop + iOS17) is able to save it successfully while running the same code. 

I see [these tests](https://wpt.fyi/results/webauthn?label=master&label=experimental&aligned&q=large-blob) are passing...
and what's strange is that `extensions.largeBlob` is defined (as in supported) but then the response keeps coming back as `extensions.largeBlob.written == false` when trying to write a largeBlob in Chrome.
Is this a Chrome bug? 

I'm testing with TouchID on macOS and FaceID on iOS.
