HTML comment cause issue functions script root


I noticed HTML comment tag <!-- --> will cause issue on themes functions.php script if it is in the root of script(not inside a function).
I was working on my themes functions.php to add some Easy Digital Downloads action/filter, which i realized purchase button will continue to loading and doesnt add product to basket.
after clearing an html comment that was in the root of script,issue solved. i need to know whats wrong with having HTML comment in functions.php root ?

(BTW my wp site is hosted on a cpanel shared host)
