Dropdown: Clicking on currently selected item no longer closes the list

[PeterHewat]

Describe the bug

Previously, clicking on any item in a dropdown list would close it even if the item was already selected. Recently, the behaviour has changed: clicking on an item in the list closes it except if it is the currently selected item.

Environment

Reproducer

No response

Angular version

17.*

PrimeNG version

Build / Runtime

Browser(s)

Steps to reproduce the behavior

Go to the documentation of the Dropdown component: https://primeng.org/dropdown
On the first dropdown, select "New York" => The item is selected and the list disappears. (OK)
Open the dropdown again and select "New York" again => The list remains visible. (not OK)

Expected behavior

On previous versions (<= 17.4.0), the list would always disappear which is what a dropdown should do regardless of which is the currently selected item.
You can check the old (good) behaviour here: https://www.primefaces.org/primeng-v16-lts/dropdown
