[DynamicSizeList] Rendering items on top of each other if height is the same as estimatedItemSize

Found a bug on #102, if my items are exactly height 50 (the estimatedItemSize value) they will all render on top of each other:

If they have any different height (e.g. 49 or 51) it works:

Ah, interesting edge case. This only holds true if every item is the exact same size as the estimated size. In this case, the list assumes there are no updates to be made. It's not handling the case where content has been rendered for the first time though.
