Monaco Editor Playground Code

// 	var vToUserEmail, vCCUserEmail,	vMessage = $("#txtNotificationText").val(), vHTMLText;
	
// 	if ($("#cmbNotificationTo").val() !== ""){
// 		vToUserEmail = $("#cmbNotificationTo").val();
// 	}
	
// 	if ($("#cmbNotificationCC").val() !== ""){
// 		vCCUserEmail = $("#cmbNotificationCC").val();
// 	}

Reproduction Steps

F1 -> Format Document
results in error
"Overlapping ranges are not allowed!"

Actual (Problematic) Behavior

Format document fails with error

Expected Behavior

Format document succeeds

Additional Context

Language javascript.
This is most likely related to formatting lines with single tab character between commented out lines.

Right click -> Format Document does not result in this error.

Start with the supplied Monaco Editor Playground link and code, then reproduce the failure with F1 → Format Document. Compare it with the right-click Format Document path and trace the formatting entry point involved in the keyboard action. Done means the reproduced JavaScript snippet formats successfully without an “Overlapping ranges are not allowed!” error.
