Chrome Data Saver Is Now Lite Mode

What's Chrome's strategy with HTTPS? The text is scarily blurry:

> And of course, Lite mode will continue to respect your privacy. When Chrome optimizes an HTTPS page, only the URL is shared with Google and other information such as cookies, login information, and personalized page content is not shared with Google. We never break secure connections between Chrome and a website.

In the past, HTTPS was always kept untouched. Since it's nowadays "HTTPS everywhere", I wonder how they decide which information is "sensitive" and which not. Don't even start with arguing that cookies are, but PNGs or JS is never sensitive.
