Toast Message not displayed in Edge after updating @angular/

Hi,

Our Toast Messages is no longer displayed in Edge after updating @angular/animations from version 7.2.6 to 7.2.12.

In the Edge Debugger I can see that an extra Class (ng-animating) and a new Style information is added to the mdb-toast-component. The new Style information is "animation:gen_css_kf_4 300ms linear forwards; display: none;".

using @angular/animations 7.2.6.

<div class="overlay-container">
<div class="md-toast-top-right" id="toast-container">
    <mdb-toast-component class="md-toast-success toast-module-opacity ng-trigger ng-trigger-flyInOut" style="opacity: 0.5;">
        <!---->
        <!---->
        <!---->
        <!---->
        <div class="md-toast-message ng-star-inserted" aria-label="The table for 'Document Type' was uccessfully saved!"> The table for 'Document Type' was uccessfully saved!
        </div>
        <!---->
        <!---->
    </mdb-toast-component>
</div>

using @angular/animations 7.2.12.

<div class="overlay-container">
<div class="md-toast-top-right" id="toast-container">
    <mdb-toast-component class="md-toast-success toast-module-opacity ng-trigger ng-trigger-flyInOut ng-animating" style="animation:gen_css_kf_4 300ms linear forwards; display: none;">

        <!---->
    </mdb-toast-component>
</div>
