Current behavior

When typing into the tags field, on Chrome and Firefox a dropdown list of available tags displays after a few characters, on Safari the list never appears.

Expected behavior

I expect the list to appear on all browsers consisently

Minimal reproduction of the problem with instructions (if applicable)

You can see this live here: WeAnimalsArchive

Start typing words in the top row - dog, cat, etc., and you should see a dropdown list of keywords in the database appear. On Safari, the list doesn’t appear, on Chrome and Firefox it appears and works as expected.

My component is as follows:

<tag-input  formControlName="dragAndDropObjectsAnd"
                        [dragZone]="'zone1'"
                        [editable]="true"
                        [theme]="'bootstrap'"
                        #tagand (keyup.enter)="onEnter($event)"
                        [placeholder]="''"
                        [separatorKeyCodes]="[32, 9]"
                        [secondaryPlaceholder]="placeholderAnd"
                        [class]="light"
                        >
                        <tag-input-dropdown 
                            [focusFirstElement]="true" 
                            [autocompleteItems]="keywords"
                            [displayBy]="'name'"
                            [identifyBy]="'id'">
                            <ng-template let-item="item" let-index="index">
                                {{ item.name }}
                            </ng-template>
                        </tag-input-dropdown>
        
            </tag-input>
