Hiding protected comments from RSS comments feed

First I Love WordPress!!

However, I have some protected pages on my site to which people leave comments.

The protected pages work fine (www.htsweb.net/projects/dashboards) but if you subscribe to the RSS comments, you can see the comments on the protected page via Chrome (https://www.htsweb.net/comments/feed/).

Firefox, for example, does what you expect and does not show the protected comments.

Any ideas on why Chrome is showing the protected comments?

Thanks, Simon
