Url without protocol are not processed correctly

[DenisBalan]

Having in meta something like

<link rel='preconnect' href='//static.hotjar.com' />
<link rel='preconnect' href='//adservice.google.com' />
	
<link rel='dns-prefetch' href='//static.hotjar.com' />
<link rel='dns-prefetch' href='//vars.hotjar.com' />

Extension shows

Expected should be:

https://static.hotjar.com
https://vars.hotjar.com

Basically protocol should be processed, not url appended to the root domain.
