[Bug] Editor placeholder using Visual Material renders incorrectly

The Forms Editor placeholder using Visual Material renders incorrectly if used in more than on sub tab page

Description

The Xamarin Forms Editor placeholder string renders incorrect (the Placeholder text size stays the same size as Text-field text size, the Placeholder text is left tabbed and off-region) when: 1. Using the Xamarin Forms Editor component on multiple tab pages 2. When rendering on IOS, it renders fine on Android 3. The text field is pre-filled with data (single or multi-line, does not matter)

(An animated image showing the problem is attached)

Steps to Reproduce

1. Create a Xamarin Forms Mobile app for Android and IOS. Add the Visual.Material nuget. Update the Forms and Visual.Material Nugets to latest.
2. Create a startup tabbed page containing at least two sub-pages
3. Place a single Editor component into a StackLayout on each tab page, set their Visual property to VisualMarker.Material
4. Hardcode the Editor components Placeholder and Text properties with some data
5. Add FormsMaterial.Init() to AppDelegate.cs
6. Build for IOS and run on the simulator (e.g. iPhone XR -12.1)
7. Notice the Editor component renders correctly in the first tab, then notice it renders incorrectly when navigating to any other tab.

(A simple sample project demonstrating the problem is attached)

Expected Behavior

The Editor component shall display the Placeholder text left-aligned and smaller as the main Text on the first line

Actual Behavior

The Editor component displays the Placeholder text clipped and the same size as the main Text on the first line
