Ion-select doesn't show item with 0 value

[Rob-Meijeren]

Bug Report

Describe the Bug
When a value is bound to a ion-select-option through the square brackets the option with value 0 is not showing its text in the ion-select

Steps to Reproduce
Steps to reproduce the behavior:

1. add a ion-select to your html with multiple options of which one has a value of 0 ([value]='0')
2. when you select the option with value 0 the select doesn't display the text of this option

However it does work when you set the value with interpolation: value='{{ value }}'

Expected Behavior
even when you bind the value with the square brackets the 0 option should show when selected

maybe related to #15420

Looks the same indeed but this is more on how the values are bound to the select-options.

I see this issue too. The bare bones example mentioned by @brandyscarney in #15420 does seem to work, but when you add Angular data binding, it fails when you select the '0' option (meaning the select displays a blank string instead of '0'). This is my example:

<ion-item>
  <ion-label>Numbers</ion-label>
  <ion-select id="numberSelect" name="numberSelect"
    [(ngModel)]="numberSelect" (ionChange)="consoleLog(numberSelect)">
    <ion-select-option [value]="0">0</ion-select-option>
    <ion-select-option [value]="1">1</ion-select-option>
    <ion-select-option [value]="2">2</ion-select-option>
    <ion-select-option [value]="3">3</ion-select-option>
    <ion-select-option [value]="4">4</ion-select-option>
    <ion-select-option [value]="5">5</ion-select-option>
  </ion-select>
</ion-item>

My ionic info:

ionic (Ionic CLI) : 4.4.0 (/usr/local/lib/node_modules/ionic)
Ionic Framework : @ionic/angular 4.0.0-beta.16
@angular-devkit/build-angular : 0.10.6
@angular-devkit/schematics : 7.0.6
@angular/cli : 7.0.6
@ionic/angular-toolkit : 1.2.0

Thanks for the issue! I can confirm this bug exists for the Ionic select and not the native select. We will look into this.
