Dropdown with filter bug selecting with arrow keys

[jure123]

PrimeVue 3.7.1

If using Dropdown with filter="true", after you type something in the filter box and start pressing down arrow keys, sometimes you won't be able to navigate through all filtered options by arrow keys (pressing arrow keys don't work in some cases).

To reproduce:

• Go to: https://primefaces.org/primevue/showcase/#/dropdown
• Click on the Dropdown under "Advanced with Templating, Filtering and Clear Icon"
• Input "g" character in the filter (-> Egypt and Germany will show)
• Press DOWN arrow key -> you can only select Egypt but not Germany
• You can also select a random country first then open dropdown again and enter a letter in filter box -> arrow keys do not work properly as well

BTW: I also tested this on your PrimeNG demo, and it works fine there, only PrimeVue has a bug.
