Mobile menu not respecting device viewport

[ryanfurrer]

Mobile menu is being cutoff by UI elements of mobile browser.

Suggested fix is to change from 100vh to 100dvh.

I changed the ul height from 100vh to 100dvh.

The fix could not be tested just yet because "on your network" was not working on my phone. Will try again when I get home.
