How can I solve the problem with the new Frosty iOS design?

Modals that used to stick to the bottom edge of the screen or the iPhone's bar now hover over the newly transparent bar, which doesn't look very good, to put it mildly.

How to move the modal down under the iPhone navigation panel?

In my case, modal windows are positioned using CSS with position: fixed; top: 0; bottom: 0;.
