Incorrect highlighting of JavaScript with template strings after dangling comma

[marcins]

I managed to find a case where template string highlighting doesn't "end" properly. Here's the minimal reproduction I was able to boil it down to (tested via https://codemirror.net/mode/javascript/index.html):

fn({
  ...blah,
});

const c = `b${c.d}`;
// ^ semi-colon onwards is "red"
const d = 'foo';

It seems to specifically be the combo of a function call, object, destructuring and the dangling comma. Removing any of those parts the highlighting works correctly.

Thanks for noticing that. Attached patch should help.
