Ionic toast issue

In my case, I have a direction to create component using ViewContainerRef and ComponentFactoryResolver.

The issue is that when I call ToastController to present a toast in the created component, the toast will show but it also show extra blank padding at the end of page (I found that the style ‘padding-bottom: 300px’ is added to

of automatically). And sometimes the extra blank will dismiss later and sometimes it is not.

The issue only happen in android device or simulator but no web and ios.

Anyone can help this issue?

The below is info from ionic info:
