Monaco Editor Playground Code

// The Monaco Editor can be easily created, given an
// empty container and an options literal.
// Two members of the literal are "value" and "language".
// The editor takes the full size of its container.

monaco.editor.create(document.getElementById('container'), {
	value: `<style>#abc {
grid-template-areas:
"abc"
"hi";
}</style>`,
	language: 'html'
});

Actual Behavior

Notice how the stings aren't highlighted.

Expected Behavior

The strings should be highlighted.

Additional Context

This is valid CSS and is used in CSS Grid: https://www.freecodecamp.org/learn/responsive-web-design/css-grid/place-items-in-grid-areas-using-the-grid-area-property. This problem occurs only when the colon is immediately followed by a newline.
