Thanks for the report.
However, that is now the expected behavior, and the change was
announced in grep-2.21.
You can use the --text (-a) option to make it match.
Here is the entry from the NEWS file:

** Changes in behavior

  When searching binary data, grep now may treat non-text bytes as
  line terminators.  This can boost performance significantly.

The --text option is supposed to only change the output, no the match.
