Syntax highlighting doesn't handle fenced code blocks correctly

This screenshot is from VS Code, but since I took the TextMate grammar from here, I guess it has the same issue:

My fix for VS Code is at Dart-Code/Dart-Code#1326 and changes from the left to the right (note: I'm no expert in TM grammar so it may not be the best way, but it seems to work):

FYI - there was a bug in Dart Code's implementation of this:

"patterns": [
	{
		"begin": "///",
		"while": "///",
		"patterns": [
			{
				"include": "#dartdoc"
			}
		],
		"name": "comment.block.documentation.dart"
	}
]

The while pattern should be ^/// so that it doesn't include the whole of the next line if it contains /// when it's not at the start (see Dart-Code/Dart-Code#1554). It's fixed now in Dart Code's master.
