Thanks Domenic, we've landed a change to remove .tentative from the test
file names:
https://chromium-review.googlesource.com/c/chromium/src/+/5967596

Gregg, IIUC "top-level->iframe(blob-from-top-level)" means the top-level
creates a blob URL and then creates an iframe where the src is that blob
URL. Similarly, "top-level->iframe(3rd-party)->iframe(blob-from-3rd-party)"
means that the 3rd-party iframe creates a blob URL and then creates an
iframe where the src is that blob URL. Neither of those cases will be
affected by this change.

Daniel, thanks for the feedback. We will collect use counts on this and
report back once the data is available (should be around mid-February). In
the meantime, we will request formal signals from Gecko and WebKit as you
recommended.

On the topic of alignment across browsers, the I2S mentions that all
navigations will remain partitioned only by frame origin, but I learned
recently that Safari and Firefox partition subframe navigations (like using
a blob URL as the src of an iframe) by storage key / the top-level as well
(and this is what was originally proposed in
https://github.com/w3c/FileAPI/issues/153). It's only top-level navigations
that remain partitioned only by frame origin. Our implementation will
follow suit. I'll update the Chrome Status description accordingly.
