Angular2Multiselect causing flicker when opening NgbModal

[chrisdlim]

I have a basic multiselect component on many pages that work fine:

<angular2-multiselect
        [data]="filter.value.items"
        [(ngModel)]="filter.value.selectedItems"
        [settings]="filter.value.settings"
        (onSelect)="filterByMultiselect(filter.value.filterName, filter.value.selectedItems)"
        (onDeSelect)="filterByMultiselect(filter.value.filterName, filter.value.selectedItems)"
        (onSelectAll)="filterByMultiselect(filter.value.filterName, filter.value.selectedItems)"
        (onDeSelectAll)="filterByMultiselect(filter.value.filterName, filter.value.selectedItems)">
 </angular2-multiselect>

However, when I open a modal (using NgbModal bootstrap 5) on a page with the multiselect on it, the page slightly flickers before the modal opens

Using:

• Angular 8
• Bootstrap 5.1.1
• Angular2multiselect 4.6.3

I'm also noticing that the modal open animation doesn't on work on pages with a multiselect.

Edit: My issue was fixed by upgrading ng-bootstrap to 9.1.1.
