Angular 7 Material Expansion Panel flicker

This guy posted a temporary work around with css, that seems to work: https://github.com/angular/components/issues/11765#issuecomment-447991348

::ng-deep .ng-animating div mat-accordion mat-expansion-panel mat-expansion-panel-header {
    height: 48px;
  }
::ng-deep .ng-animating div mat-accordion mat-expansion-panel div.mat-expansion-panel-content {
    height: 0px;
    visibility: hidden;
}

I left away the ::ng-deep and added it to my global styles.

This is a bug. and there's an open issue for it.

It is caused when the expansion panel is contained and animated.
