The emmet expansions ! and html:5 both produce this expansion:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
</body>
</html>
The <meta http-equiv="X-UA-Compatible" content="IE=edge"> meta tag is unnecessary and should be removed. It was last used in IE10 to turn on compatibility mode and now as even IE11 is dead, we can safely remove it.
It was initially removed in 2019: #80923
Then added back in: #108119
Then suggested to remove it again in 2021, which Im pretty sure incorrectly says it was needed for ie11: #128374
Now that all IE is dead, let's get rid of it!
