Steps to reproduce the behavior
Occurs in multiselect component
Expected behavior
When filterFields is provided:
<p-multiSelect
[options]="items"
optionLabel="name"
[filter]="true"
[filterFields]="['name', 'code']">
</p-multiSelect>
The filter logic should only match against the fields specified in filterFields (name, code).
Results should be filtered based on those fields instead of using default fields or implicit behavior.
