[iOS] Editor Placeholder misaligned vertically

[hartez]

I notice the placeholder is a bit off center... However, this seems to be an exact copy from Forms so might be a bug there. Not sure if we need to fix that here. But if it is an easy fix then maybe?

added a Editor can validate the same issue on iPhone 13 pro max 15.2.

To fix the position and probably the font size you could use:
EditorHandler.Mapper.AppendToMapping("PlainEditor", (handler, view) => { // relates to: https://github.com/dotnet/maui/issues/585 handler.PlatformView.Subviews.OfType<UILabel>().First().Font.WithSize((System.Runtime.InteropServices.NFloat)view.Font.Size); });
