Retrieves a cell area’s initial minimum and natural height.
this will store some geometrical information in context along the way; when requesting sizes
over an arbitrary number of rows, it’s not important to check the minimum_height and natural_height of this call but
rather to consult get_preferred_height after a series of
requests.

the CellAreaContext to perform this request with |
| widget |
the Widget where this will be rendering |
| minimum_height |
location to store the minimum height, or null |
