PrimeNG Bug: Accordion tabs show content as if opened when closing and opening dialog

[blake-w]

Primeng version: 17.18.10

Recreated the issue at Stackblitz: https://stackblitz.com/edit/llx7yx-s6d7mc?file=src%2Fapp%2Fdialog-basic-demo.html,package.json

Steps to recreate:

1. Open dialog
2. Close dialog
   • Note: you can see the accordion open all accordion tabs as dialog closes
3. Open dialog
   • Note: all accordion tab content is visible but the collapse/open icon is still in "closed" state

I tried overriding the activeIndex list upon opening the dialog, but there was no difference.

You can further see this behavior by setting the activeIndex list to all indices (to default to open state).
Open the dialog.
Collapse 1 or more accordion tabs.
Open and close the dialog twice.
It will show the previously collapsed accordion tabs as "opened" despite not showing their content.
