Dropdown attr aria-expanded missing because undefined value

[ramonrangelc]

Hello we are using primeng v17.7.0 There is an issue with dropdowns accessibility. From dropdown.ts code overlayVisible is a Nullable and [attr.aria-expanded]="overlayVisible" so by default aria-expanded is undefined, causing a critical accessibility issue. A simple undefine validation on dropdown template code should fix the issue: [attr.aria-expanded]="overlayVisible ?? false"
