Dropdown: In PrimeNG 16.7.1 interacting with dropdown causes panel to scroll

[rosenthalj]

Describe the bug

If a horizontal scroll bar is present, when a user clicks on the dropdown component or uses the mouse key to navigate the dropdown menu options, the panel containing the dropdown will scroll to the beginning of the visible region.

This is a similar to issue #13390 that was fixed on September 26th.

The first video demonstrates the problem when the user clicks on the dropdown to open and then clicks on the dropdown's "down carrot icon" to close.

The second video demonstrates the scrolling problem when the user navigates the dropdown menu options using only the keyboard .

Hi,

We've fixed two issues you've mentioned with the version 16.7.2, they both works as expected in the latest version.
Here is the example containing both issues happening in 16.7.1 https://stackblitz.com/edit/z78n8c?file=src%2Fapp%2Fdemo%2Fdropdown-basic-demo.html

Closing this and #14078 since it's already fixed within 16.7.2.

Thanks for reporting the issue!
