Make sure that data.last_minimum_size is consistent with `get_combi…

…ned_minimum_size()` at the same time

Move the code for switching `data.minimum_size_valid` in `Control::update_minimum_size()`
to `Control::_update_minimum_size()`, make sure to switch `data.minimum_size_valid` to
`false` only before updating `data.last_minimum_size` , so that it will remain consistent
with `get_combined_minimum_size()`.
