paren match highlighting is slightly broke

Paren match highlighting often does not work when syntax is set with 
font-lock-syntactic-keywords.
The following 2 lines comprise the entire test file

-- turn -*-tal-*- mode on here.
BEGIN   BEGIN   BEGIN   END  !TEST!  END   END

I've included the properties of these 2 lines below.
In prior versions (21.2.1 for example) this worked fine.  
In this version, placing the cursor before any of the BEGIN keywords
causes the corresponding END to light up ONLY if there are no intervening 
comments.  In the example, only the matching pair prior to the !TEST!
comment light up.  Not even the B lights up as unmatched on the other
2 pairs.  It doesn't seem to make any difference where I put the comment.
Comments effectively prevent paren matching from occurring.

It may help to know that the problem also occurs in this example

BEGIN   BEGIN () !TEST!   BEGIN   END  END   END

but in this next example

BEGIN   BEGIN (!test!) !TEST!   BEGIN   END  END   END

Everything works fine.  All the begin/end pairs light up correctly.

Here are the properties of the original 2 lines.
