I see that it messes up colorization. Not sure if it's invalid or what:

@luqimin if you a leave space on both sides of --------blablabla--------- just like <!-- --------blablabla--------- --> instead of <!----------blablabla-----------> it works perfectly well(It's a best practice as well).
It'll also work if you add one more - on the right-hand side of the blablabla, just in case if you don't want to leave any space in-between.

I wouldn't recommend typing <!-- --> manually to comment lines. better to use Ctrl+/ to avoid any DOM rendering issues.

Multiple hyphens in comments are valid in HTML5 standard:

8.1.6. Comments

Comments must have the following format:

1. The string "<!--"
2. Optionally, text, with the additional restriction that the text must not start with the string ">", nor start with the string "->", nor contain the strings "<!--", "-->", or "--!>", nor end with the string "<!-".
3. The string "-->"

In fact, according to the parsing rules, <! >, <!-- <!-- --> and <!-- --!> are parse errors but recoverable and also represents HTML comments.

Of course, they are invalid in XML standard, but HTML is not XML.
