Hi @BABA983 thank you for making this PR and I am really sorry for the wait time. I will have a look right now at the PR.

Hi I looked at the PR. I think the solution you propose is a bit finicky and could lead to unexpected issues. I think instead what we could do is simply not to go through the block comment logic when the cursor is inside a comment. This alternative solution has also been mentioned by one of my teammates on the issue this PR is closing. To verify the token type at a specific position you can use the following code:

model.tokenization.forceTokenization();
model.tokenization.getLineTokens(lineNumber).getStandardTokenType(tokenIndex)

The standard token type can be one of these values:

export const enum StandardTokenType {
	Other = 0,
	Comment = 1,
	String = 2,
	RegEx = 3
}
