RE: HTTP3 regression in curl 7.84.0

Yes, it looks like the same issue. Some problems with ngtcp2 0.6.0.
Not easy to bisect though as ngtcp2 API keeps changing and libcurl must adapt...

I belive you experience the same thing as being discussed here:

It would be very useful if someone could try a bisect to figure out where it broke.
