Attempting to view a model's info via press-and-hold results in the modal window being stuck in place. The only way to close the modal is to tap in an area above the selection menu area (including inside the modal window). This prevents quick review and selection of models as the process has to be started from scratch for every viewing.
Ideally the modal is able to close without closing the selection menu. A close button on the modal may be more intuitive for mobile usage.
