Parent checkbox state incorrect when TreeSelect is being filter

[bon-vivant]

Describe the bug

On TreeSelect Filter, filtering selection so that a node with multiple children options is filtered down to displaying just one child option, then selecting the child, causes the parent checkbox to display fully-selected (checked) icon instead of the partially-select (minus) icon. Clearing the filter will redisplay the other children options but parent checkbox is still showing fully-selected (checked) icon:

Environment

Found on

PrimeNG 14.0.0
Angular 14.1.1

but it was probably an issue in PrimeNG 13 when filter was introduced to the TreeSelect component.

Steps to reproduce the behavior

1. Open TreeSelect dropdown
2. Filter a multiple children node down to so that at least one child option is filtered out
3. Select all available children in the node until parent checkbox shows fully-selected (checked) icon
4. Clear the filter so that all children are now visible and nothing is filtered out
5. Observe that parent checkbox is still displaying fully-selected (checked) icon

Expected behavior

Parent checkbox should be displaying partially-selected (minus) icon either by step 3 or step 4.

If at least one but not all child options of a node are selected, parent checkbox should display partially-selected (minus) icon. Parent checkbox should only display fully-selected (checked) icon when all its children options are selected.

Can you reopen this issue? This is still an issue in 17.6

I don't see a way to reopen the issue on the page (screenshot of what I'm seeing), just a Comment button (screenshot of what I'm seeing).
@mertsincan are you able to reopen the issue or should a new issue typically be created in this situation?
