Ionic-framework: bug: ion-textarea autoGrow=“true” on modal, work only the first time

[IterationCorp]

Expected behaviour:
Each time the ion-textarea should be the same size.

Actual behaviour:
I have a strange behaviour with ion-textarea autoGrow="true" that was introduced in ionic 4.4, the first time the autoGrow is made correctly. The 2nd time the textarea is less than 1 row. We can't even see the text. This bug is only on "modal".

I open the modal like this

```
displayModal(data) {
this.modalCtrl.create({
component: EventDetailModalComponent, componentProps: {
event: data.appointmentData,
timeFormat: this.timeFormat,
dateFormat: this.dateFormat
}
}).then(modalElement => {
modalElement.present();
}); }

And close like this :

   `onCancel() { this.modalCtrl.dismiss(); }`
View contains :

{{'DESCRIPTION' | translate }}


```
For info, the text is inserted manually by the programme in value="x", not entered by the user.

I'm running the last version of ionic ("@ionic-native/core": "^5.11.0") and Angular (8.2).
Same problem tested on last version of Chrome, Safari and FireFox on Mac.

This was already reported on "stackoverflow":

They came to the conclusion that should be a bug.

Confirmed. Still present in @ionic/angular: 4.11.1 It's not an onChange issue. Because the modal is presented with different text examples. I think it's a lifecycle issue (initialize order with maybe async parts). e.g. reset the value with setTimeout in ngOnInit in a second. (simply add a space to the string.) But why is this always working on the first time?

One workaround could be using contenteditable instead of textarea. With a few styles like outline: 0 and line-height 1.5em. etc. But it's more recommended to fix this bug.

Hello, this issue is still present in @ionic/angular: 5.0.5.

For some reason or another, I am only seeing this on md, not ios.
