	* `tagName` is the closing tag which will prompt us to stop skipping

	* `tokens` is the array of tokens generated by HTML5Tokenizer which

	* `i` is the index immediately after the opening tag to skip

	* `skippedTokens` is an array which skipped tokens are being pushed into

	* Assumes that i is the first token after the given opening tagName

	* The closing tag will be skipped, but nothing after it

	* Will track whether there is a nested tag of the same type
