Paul,

I was at Aero Expo and found three Wankel makers there.  When I look at the P port it seems that there is a chance for the gas to pass from one side of the apex to the other side right at the p port.  Is this an issue?  I guess not as people would have thought of this long time ago.

Not a problem over 4500 RPM.
Usually the pressure in the intake is higher than the pressure in the exhaust.

It is like a jet engine in that regard. The air pressure from the compressor
section is higher than the pressure from the combustion area so air flows in the
front and out the back.
