bug: stacked label causes glitchy page transitions on ios

[mirkonasato]

Bug Report

Ionic version:
[x] 5.x

Current behavior:
Have an app with list and detail pages. Detail has an <IonLabel position="stacked />. After navigating to the detail page, the view appears to "zoom out" a little bit. After navigating back to the list page, the view zooms in again.

It's small but clearly noticeable. Please see this video.

This only happens with position="stacked".

Expected behavior:
Should work smoothly, like with position="fixed" or "floating".

Steps to reproduce:

Clone this repo: ionic-stacked-sample

Run npm install, build, deploy to the iOS simulator. Click on a list item and back.
