Scrolling Array Param in ParamsList Faulty

Scrolling through an array parameter in the paramslist window stops at the 2nd last array entry.
If connected to a menu element on the macro editor, the macro menu does scroll to the last item though. So not a train smash.
This only seems to be true for script parameters as the Zone parameters scroll correctly.

Clicked selection of the last element in paramslist works fine.

This example will only scroll to “item 9” in the paramslist.

array = {}
for i = 1, 10 do
	array[i] = 'Items ' .. i

defineParameter('ArrayParam', nil, 1, array)
