fix(Popup): filter out NaN values from Popper's styles

[kuzhelov]

Problem

The problem is Popper's calculation logic outputs NaN values for the cases where height (or width) of reference element is 0. However, this is pretty common case for test environments, where styles may not be rendered/applied to Popup's trigger - and, as a result, it will have height of 0.

This, in its turn, results in invalid styles being applied to rendered div element, as calculated by Popper styles are just passed to slot's div component, with NaN values being there:

Resolution strategy

This PR provides fix that will guarantee that simple mount of Popup component in client's tests won't result in console errors - by removing style props that has NaN as value.
