navbar not easily clickable on iPhone without home button

[ttraenkler]

On iPhone models without home button (iPhone X, XS, 11 Pro), the navbar is not clickable directly, but two clicks are needed.

The reason is on these models this area is a control area that replaced the home button for swiping up to close the app or left right to switch to another app. In order to solve this, the navbar needs more bottom padding on these models.
