sorry, I've still not been able to replicate this, it's probably because I don't use chrome for general browsing.
Ben had an idea that it might be related to chrome prefetching content, you can turn this off in your settings and see if it makes a difference:
Chrome prefs -> ( chrome://settings/) -> Privacy and security -> Cookie and other site data -> turn off toggle for 'Preload pages for faster browsing and searching'
Can't think of anything else, can't be a script etc. It'll be in a similar place/wording under edge.
