Much blank space at the content's bottom with Infinite-Scroll


Hello. Why so much blank space exist in ion-content when I use infinite-scroll? Example on screen (it’s bottom of device):

my code:

	<ion-refresher (ionRefresh)="refreshRoutes($event)">
	<ion-card class="route-result" *ngFor="let route of routes" (click)="buyTicket(route.ride_segment_id)">
	<ion-infinite-scroll (ionInfinite)="showInfiniteRoutes($event)">

height of this block set up in css rule:

ion-infinite-scroll-content {
      min-height: 84px;

Is it normal for this component? I think this block wouldn’t have so much height.
