Ionic 2, how to make an ion list, grow from bottom to top?

Question

Here is the gist of my code:

<ion-content>
  <ion-list>
    <ion-item *ngFor="let item of array">{{item.name}}</ion-item>
  </ion-list>
</ion-content>
<ion-footer>
  <ion-searchbar (ionInput)="search()"></ion-searchbar>
</ion-footer>

The idea is that at the bottom of the screen there is a search bar with a list above it, which changes depending on the entrance to the search bar. However, this code will force the list to fill up from top to bottom with a lot of empty space between it and the search panel if there are several elements. I would like the list to hug the search bar (mostly aligned to the bottom of the ionic content), but still remain scrollable inside the ionic content. What are some ways to do this?

// First add ViewChild and Content imports
import { ViewChild, Component, ViewEncapsulation } from '@angular/core';
import { NavController, Content } from 'ionic-angular';

@Component({
  selector: 'page-home',
  templateUrl: 'pages/home/home.html',
  styles: [`
    .scroll-content {
      display: flex;
      flex-direction: column;
    }
    .scroll-content ion-list {
      margin-top: auto;
      margin-bottom: 0;
    }
  `],
  encapsulation: ViewEncapsulation.None
})
export class HomePage {
  @ViewChild(Content) content: Content; // <-- get a reference of the content

  count = 4; // for demo
  appName = 'Ionic App';
  array = [
    { name: 'item-1' },
    { name: 'item-2' },
    { name: 'item-3' }
  ];

  constructor(private navController: NavController) {

  }
  search() {
    console.log('searching...');
  }
  add(number) {
    let itemNumber = this.count;
    this.array.push({ name: 'item-' + itemNumber });
    this.scrollToBottom(); // <- when the new item is pushed, scroll to the bottom to show it
    this.count += number;
  }

  scrollToBottom(){
    // use the content dimension to obtain the current height of the scroll
    let dimension = this.content.getContentDimensions();

    // scroll to it (you can also set the duration in ms by passing a third parameter to the scrollTo(x,y,duration) method.
    this.content.scrollTo(0, dimension.scrollHeight);
  }
}
