	<!--
	Code such as this:
		while ( ( $foo = $foo->nextSibling ) && someCondition( $foo ) ) { … }
	is often convenient when working on DOM tree structures, which we do a lot of in this extension.

	It's particularly helpful in combination with Phan, which can infer that `$foo` is non-null from
	the code above, but it can't infer that `$foo->nextSibling` is non-null in code like this:
		while ( $foo->nextSibling && someCondition( $foo->nextSibling ) ) { … }

	When the variable is the only condition, we add extra parentheses to indicate that it isn't a
	typo for `==`, which is a convention borrowed from C:
		while ( ( $foo = $foo->nextSibling ) ) { … }
