Bug Report

Ionic version:
[x] 4.x

Current behavior:
When setting a position absolute to the ion-spinner won't hold in place as it used to but is now moving slowly to the right.

Expected behavior:
Spinner stays in place even with absolute positioning

Possible regression:
Ionic v.4.7.1 -> all good, spinner stays in place
Ionic v4.8.1 -> spinner is moving

Related code:

<ion-content>
    <ion-spinner color="primary"></ion-spinner>
</ion-content>

ion-spinner {
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
}

Other information:

I observed the behavior in an Angular app as well in a Stencil PWA, therefore I would say it's a core issue.
