Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `a = f'''
line1
line2
print('error')
'''`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: 'python',
	automaticLayout: true,
});

Reproduction Steps

If f'''xxxxxx''' is used to represent a multi line string, only the first line is recognized as a string

Actual (Problematic) Behavior

The second to fourth lines should be highlighted as strings, but in reality, only the second line is highlighted as a string

Expected Behavior

Highlight multiple lines of string normally

Additional Context

No response

Start with the linked Monaco Editor Playground and its TypeScript reproduction using the Python language mode. Confirm that the multiline f-string highlights only its first line, then trace the Python syntax-highlighting behavior involved. Done means all lines inside the multiline string, including the line containing print('error'), are highlighted as string text.
