Add missing whitespace at the bottom of the features list

[tomasMizera]

The button "create feature" is normally floating above the features list. This is desired, but once you scroll to the end of the list there should be some white space for the button so it does not overlap with the last entry.

It sounds like this line is broken as it does not add the needed vertical space (height of the "create feature" button)

Line 76 in 72fe93a

height: __style.margin20 + ( root.hasToolbar ? 0 : __style.safeAreaBottom ) + ( addButton.visible ? addButton.height : 0 )

Findings: there already is a space and works fine if you scroll slowly and the button doesn't overlap the last feature, but when you scroll fast it rebounds the last feature to be below the floating "add feature" button.
