Ah I see it in that case. I think it will parse the opening < as a JS operator. But probably works in a browser.

I don’t think this issue will be fixed by https://github.com/Microsoft/vscode-textmate/pull/85, as I look at this, this specific issue is a limitation of TextMate, which lacks a construct that acts something between the Begin/End rules and the Begin/While rules. Begin/While rules solve a very specific problem, but cannot be used here. We really could use a Begin\Until system. Unlike a Begin\While rule, a Begin\Until rule would capture all the content of the line up to the point the Until pattern matched and process it with the current rule stack, before restoring the stack to the condition it was in before the Begin/Until rule began.
