When typing enter after a double slash, the line-breaking javascript code is automatically commented out by mistake

What happen

I found this issue in the Insider version, but it also reproduced easily in the web version.

I discovered this when I tried to move object's properties to a new line.
There is a regular expression ending in a slash before the cursor, and it just so happens that there are two consecutive slashes in the text. Causing the text after the cursor to be recognized as a line of comments?

Example Code

const a = {
	// regex ends with   ↓↓ 'double' dash
	str: ''.replace(/^\.\//, ''), i_wiil_be_commented_if_you_keyup_enter: 'what?!',

	// not ends with      ↓ 'double' dash
	str: ''.replace(/^\.\./, ''), i_wiil_not_be_commented_if_you_keyup_enter: 'well',
};

@aiday-mar maybe can add backslash to the regex as well (?<!\\\\)

Hi @RedCMD thank you for the idea. Yes we should do that.
