This has changed in e3fdbcc8e1 (parse_mailboxes: accept extra text after
<...> address, 2016-10-13), released v2.11.0 as you noticed:

The problem is that we now accept list of emails instead of just one
email, so it's hard to define what "comments after the email", for
example
Cc: <foo@xxxxxxxxxxx> # , <boz@xxxxxxxxxxx>
Is not accepted as two emails.
So, just stripping whatever comes after # before parsing the list of
emails would change the behavior once more, and possibly break other
user's flow. Dropping the garbage after the email while parsing is
possible, but only when we use our in-house parser (and we currently use
Perl's Mail::Address when available).
So, a proper fix is far from obvious, and unfortunately I won't have
time to work on that, at least not before a while.
OTOH, the current behavior isn't that bad. It accepts the input, and
extracts a valid email out of it. Just the display name is admitedly
suboptimal ...
