Description

When using Editor.AutoSize="TextChanges", the Editor is expected to resize dynamically based on the text content. However, on iOS and MacCatalyst, while the Editor content may update, the placeholder layout does not update correctly during resizing.

Steps to Reproduce

• Create an Editor with both Placeholder and AutoSize="TextChanges". EditorControl.zip

• Run the app on iOS or Mac.

• Add and delete text to trigger auto-resizing.

• Observe that the placeholder does not adjust or align correctly.

Expected Behavior: The placeholder should remain properly aligned and visible as the Editor resizes dynamically.

Actual Behavior: The placeholder does not reposition or resize in sync with the Editor. The placeholder appears misaligned or clipped when text is added or removed.
