overridden function in module is not covered (affects method modifiers and friends)

In the following example, sub _do is not recognized at all.

$ cat Moop.pm
package Moop;
sub _stop { 10 }
sub _do { 5 }
my $old = \&_do;
*_do = sub {  $old->() . _stop };
1;

$ cover -delete && perl -I. -MDevel::Cover -MMoop -E 'say Moop->_do' && cover
[...]

Oh yeah, just in case it's not clear. If you convert Moop to a script and run it directly instead of use()ing it, _do is recognized.
