Ionic search will not show overflow

Hello guys,

I built a search bar and list item entries based on info here.

I realized when I populate listing page with

  <ion-list style="background: black; color: white;" *ngFor="let item of items">
                                     <ion-item style="background: black; color: white;" >

my page automatically hides overflow… it can’t display more item than 5, it doesn’t allow me to scroll. There 20 items but I can see only the ones which are on top.
Why does this happen and how can I enable overflow for items from data entry?

This search page is inside ion-segment… when I manually populate without using *ngFor tag, it allows me to scroll.
