How to resize a modal form to match the visible form elements?

Question

1C

Actually introductory:
1. There is a modal dialog (quantity input during selection)
2. In different situations, some elements of this form can be visible / invisible, that is, the composition of visible elements changes.
The problem is that the size of the form 1C remembers from the previous opening. And if, for example, to make some elements visible, then the size of the form - DOES NOT INCREASE. Scrollbars appear, you need to resize the dialog manually.
Actually form attribute "Height" - does not work. Neither on the client nor in the server call. The props change. But the actual size of the form is not.
I'm looking for advice from those who have solved this problem.
