Tests for errors are not running

 final checkParseErrors = false; 

Many of the tests start failing if we enable error checking.

Further, the tests against error only check the number of errors:

html/test/parser_test.dart

Lines 63 to 69 in 2599afe

 if (checkParseErrors) { 
   expect(parser.errors.length, equals(errors.length), 
       reason: '\n\nInput:\n$input\n\nExpected errors (${errors.length}):\n' 
           "${errors.join('\n')}\n\n" 
           'Actual errors (${parser.errors.length}):\n' 
           "${parser.errors.map((e) => '$e').join('\n')}"); 
 } 

It really should be checking the content too.
