This doesn't seem to work any more. I tried disable VA, modify the file, enable VA and restarting VS.
I changed it to "Style"="Float" but my cloned results still show up in the tabs.
I also tried setting to "Style"="Floating" with the same results.
I also tried manually floating some results before closing VS to see if there was a difference. No change in the next Clone - still tabbed.
Maybe VS has cached that setting elsewhere and I'm out of luck.
Here's the current content:
