menuShouldScrollIntoView does not scroll all menu into view #4615

React-select with menuShouldScrollIntoView set to true does not scrolled into view properly.
Although menu is scrolled into view, last options are still invisible.

On the screenshot below, only option 1 to 4 is visible and options 5 and 6 are not. Parent size is expanded to accommodate full menu and parent can be scrolled manually to see full menu.

Sandbox is here https://codesandbox.io/s/reactselectscrollintoview-44b7n

To reproduce:

1. Make sure, that react select is located at the very bottom of the window, Just above the footer. There should be no empty space between react-select and footer. (it may be required to decrease browser window size)
2. Open react-select.
3. Observe, that although container has been scrolled down, it is not scrolled down enough to include all options. To see last options, manual scrolling of the container is required.

Expected result: container is scrolled to accommodate all options.

Also, if header and footer will not be present, parent will be scrolled properly.
