Not offering any solution, just an observation of the problem and
annotating the report.

What we see on the second line is the beginning of peeled
v5.0-rc2^{} up to the "acd13" (that is, the first 19 bytes of the
line), followed by the full line for peeled v5.7-rc2^{} (which
begins with "ae83d").  12407 bytes in between are missing, which
is even more puzzling as it is not a nice round number.

I wonder if this is "less" misconfigured and misbehaving.  Did the
user after seeing v5.7-* tags scroll back with 'b' or something?

If the output (including the 2>&1 redirection) is sent to a file and
then "cat <that-file" is invoked, does the same thing happen?  How
about "cat <that-file | less"?
