I've successfully found a way to reproduce this issue. After uninstalling the Chrome extension "Revolut Shopper" the memory leak stopped. Since not everyone experiencing this problem uses Revolut Shopper, it might be one of the extension APIs that is causing issues.
How to reproduce
Install the "Revolut Shopper" from the Chrome Web Store and check your memory usage. You might have to log in to start the memory leak, but I'm not 100% sure.
