A.F....... [ZBX-7832] fixed screen item row- and colspans not being adjusted when reducing the size of a screen

Before the fix:
- When reducing the size of a screen or deleting a row or column, the row- and colspans of screen items have not been properly adjusted. That is, if we delete the last column of a screen, and some element with rowspan set was displayed in that column, it would be displayed out of bounds of the screen.
 
 After the fix:
 - When deleting a row or column, the row- and colspans of the items, that are displayed in these rows or columns, will be reduced to fit on the screen.
