mobile issues

[tnrich]

• a feature can't be clicked when in mobile (same with other annotation types and the editor itself)

this is due to react-grid-layout/react-draggable#728 specifically this line:

    // Prevent scrolling on mobile devices, like ipad/iphone.
    // Important that this is after handle/cancel.
    if (e.type === 'touchstart') e.preventDefault();

• a feature can't be double clicked to be edited when in mobile (same with other annotation types)
• a blank seq can't be edited while on mobile. The insert seq pop-up doesn't have a way of coming up since it currently only is activated via typing
