 This method force recomputes the item sizes after the specificed index (these are normally cached).
 
 `VirtualList` has no way of knowing when its underlying data has changed, since it only receives a itemSize property. If the itemSize is a `number`, this isn't an issue, as it can compare before and after values and automatically call `recomputeSizes` internally.
- However, if you're passing a function to `itemSize`, that type of comparison is error prone. In that event, you'll need to call `recomputeSizes` manually to inform the `VirtualList` that the size of it's items has changed.
