This seems to be working for me. Did you open the documents separately (using Ctrl+O for example) in new tabs? If the pages are related in any way, for example opened using a link from another page, then they will run in the same process as that page.
Hi Bob, Strangely I can't reproduce this issue either on the latest Nightly version (2017-03-16). I opened the documents separately by drag and drop from my Desktop and I even used clean profiles. I'm marking this as Resolved Worksforme and I'll keep an eye on this issue. Thanks for taking the time to look into it.
