Strange Property Size on First Layout

[Noeski]

Not sure if this is a bug in Unity but this only seems to happen with ReorderableArrays where the first time the inspector is rendered it uses the wrong height and the second render corrects it.

I've printed out the height returned by ReorderableDrawer which is always correct so I'm wondering if this is just an issue in Unity 2019.3 or if there is some way to fix this?
