Not only menu for selection operators is affected by that bug. For example Add Mesh, Curve etc. Suffer too:

Everything is greyed out until you hover a cursor over. Then, if you change some value, it will be greyed out again. Again, only when compositor is on.

The same issue exists in 2.79, and it's a weak design in the compositor.

Any change in the 3D viewport causes a refresh in the compositor, which in turns blocks any user interaction while working for thread safety reasons.

For now the compositor is really mostly designed to be used in isolation and not side-by-side with modeling in a 3D viewport.
