Unhandled case in unescapeHTML

I got unexpected results when unescaping this string
'"!@#$%^&*()_+{}|":?><~T"est"'

Using the original code, I saw that match and p1 was not correct.
'"@#$%^&_()_+{}|":?><~Test"'.replace(/&([^;]+);/g,function(match,p1,p2,p3){console.log(match + '-' + p1 + '-' + p2 + '-' + p3); return 'boo';})
ORIGINAL RESULT:
&_()_+{}|"-*()_+{}|"-6-"@#$%^&*()_+{}|":?><~Test"
""@#$%^boo:?><~Test""

I expected only to get " for match.

After I looked at the code, I realized the regex was wrong.
Here is the CORRECT REGEX
/&(\w+[^;]|#\d+[^;]);/g

I tested that is still handled &gt; correctly
'"!>@#$%^&_()_+{}|":?><~T"est"'.replace(/&(\w+[^;]|#\d+[^;]);/g,function(match,p1,p2,p3){console.log(match + '-' + p1 + '-' + p2 + '-' + p3); return 'boo';})
>-gt-2-"!>@#$%^&_()_+{}|":?><~T"est"
"-#34-20-"!>@#$%^&*()_+{}|":?><~T"est"
"-quot-31-"!>@#$%^&*()_+{}|":?><~T"est"
