First launch on large directory, the tree will not scroll down

[raguay]

Bug description

When Onivim2 launches in a directory that is very large, It will only scroll upwards and not downwards until I select another directory in it. Then is scrolls fine.

Steps to reproduce

Open Onivim2 in a large directory on macOS. Before clicking any other directory or file, try to scroll down the list.

What happens

It will not scroll downwards. Scrolling upwards will bring the topmost directory down the screen until it is at the bottom.

Expected results

Being about to scroll up and down freely.

BTW: This happens in the release version and the latest compile from github.
