p-dropdown: selected item is not changing when typing the first character of the items in the list

[av-code-crafter]

Describe the bug

Before primeng version 16, when we just focus on the dropdown(with the drop down panel closed) and type the first character in the list, it used to change the selected item.

For example check the behavior in version 15:
Recording-20241001_121315.webm

But after version 16 this behavior is changed. The selected item doesnot change when typing first character of list items.

How can we achieve the same behavior ?

You can set selectOnFocus to true in order to have the selection set correctly. However, the panel will be shown. So you effectivly have to confirm the selection with either tab or enter.

I have create a PR to add the property autoShowPanelOnPrintableCharacterKeyDown. In combination this restores the original behaviour.
