selection/deselection during maya style camera zoom

When I use maya style zoom with LMB+MMB I'm getting selection and deselection behavior relative to the mesh, sub component etc. most often what happens is I lose my selection or the selection is replaced as I zoom in or out with the two mouse buttons. Using the the right mouse button for zoom works without issue. I have a lot of muscle memory with the two buttons though...
P.S.
I've been testing out nvil and it is great overall.

Fixed.
