Another session cookies issue (#1545).

Error report counts by date, exact blocked reastatic.net subdomain, and site domain:

Any tips to reproduce? I've created an account on realestate.com.au, and I can see s1.rea.reastatic.net on that page after I log in (under "does not appear to be tracking"). I can also see reastatic.net subdomains on property.com.au, also marked as non-tracking, but I don't see them on any of the other sites.

I visited https://www.realcommercial.com.au/for-sale and https://www.property.com.au/buy, which got me two strikes. Then I visited https://www.realestate.com.au and searched for something ("Sydney") and the results page got me three strikes. Debug output:

DNT header test fixed in #2047.

This one looks good too. I noticed reamedia.com.au pop up as a potential tracker on realestate.com.au, but it doesn't look like that domain breaks anything.
