That appears to have been fixed since 2011:

C:\usr\local\share\PassThru\perl>perl -Mwarnings -Mstrict -MConfig -le
+ "my $cmd = q|C:\Program Files\Mozilla Firefox\firefox.exe|; open my 
+$fh, '-|', $cmd, '--version' or die $!; m
y $out = do { local $/; <$fh> }; close $fh or die $! ? $! : qq(\$?=$?)
+; print $out; print $Config{myuname}"
Mozilla Firefox 61.0.2

Trying to narrow it down a bit, using berrybrew to help me, it appears it was sometime between v5.20 and v5.26:
