I would like to add a grammar rule similar to the one found here. What that rule does is enable VSCode's JSON editor when it encounters an html file with
<script type="application/json">#Edit JSON</script>
What I would like is the same JSON editor support whenever it encounters a html attribute in this form:
<my-chart data='{"hello": "world"}'></my-chart>
In other words, any attribute that uses single quotes, inside of which it starts with a { and ends with a }, or starts with a [ and ends with a ].
Any suggestions what that should look like?
