Monaco Editor Playground Code

function alpha() { 
	;
}

function beta() { //Comment
;
}

Reproduction Steps

1. Paste the following code in the playground:

function alpha() { 
}

function beta() { //Comment
}

2. Place the cursor at the end of the line with alpha() function header.
3. Press Enter.
4. There is an auto-indentation for the function body
5. Now, pace the cursor at the end of the line with beta() function header.
6. Press Enter.
7. There is not an auto-indentation.

Actual (Problematic) Behavior

A trailing comment on the function header prevents Monaco from applying the auto-indentation.

Expected Behavior

Both of the function bodies should receive the auto-indentation.

Additional Context

The equivalent bug exists for the following languages, checked on the Home page of Monaco:

• Python
• C
• C#
• Java
• Go
• PHP
• Rust

I have only verified these languages so far, therefore the list should not be considered exhaustive.
