For once eBay may be correct, that it is a glitch. In any case, eBay doesn't just show recently viewed items, it shows unwanted "suggestions" based on previously viewed items. Perhaps this is what's happened? It's unlikely to be any form of malicious activity if it has continued even after changing your password.
Another possibility is that it's browser related, so I'd try clearing your browser cache and cookies, then restarting the browser. This often cures browser problems.
