Broken in [email protected]:

Current behavior
In versions older than 3.9.1, Dropdown does not display list items when reopened after item selection > #14

Expected behavior
Dropdown should display the list of items and scroll to selected item than reopening after selecting an item.

Minimal reproduction of the problem with instructions
Open Dropdown and select item > #14. Reopen Dropdown. Dropdown will show an empty list and the scroll bar stays in the top position.
Open Dropdown and select item #14. Reopen Dropdown. Dropdown wil scroll to item #14 but will not show items > #14.
The same error is seen in lazy and not lazy cases.
Also this error is reproduced on https://primefaces.org/primevue/showcase/#/dropdown

What is the motivation / use case for changing the behavior?
