Summary
This PR adds compact data for iframe credentialless features. See my research document for more information about this, and the overall scope of the work.
Note: I have stated the features as
"standard_track": false
for now. There is a community group report at https://wicg.github.io/anonymous-iframe, but this isn’t a proper specification, in terms of specifying API additions, behavioral changes to storage, etc. I think it'd be better to and wait until the open PRs on the other specs are merged. See:Test results and supporting details
Demo available at https://anonymous-iframe.glitch.me/.
I tested this in Chrome, Firefox Nightly, and Safari Preview. No support in the latter two yet.
