How do I prevent my ref callbacks from being called twice in ReactUMG?

Avoid using inline arrow functions for refs. Bind your ref handler in the constructor or use a class method to ensure the function reference remains stable across renders.

Does this skill help with UI performance?

Yes, by providing patterns for stable ref callbacks, it prevents unnecessary logic execution and potential memory leaks during the React render cycle.

What is required for Dark Theme colors to appear in EditableTextBox?

You must set ColorUseRule to 0 for all SpecifiedColor properties and use DrawAs: 4 (RoundedBox) for the background image to render correctly.

Why don't my ComboBoxString options show up using DefaultOptions?

In ReactUMG, the DefaultOptions property often fails to initialize correctly; you should use a ref with nativePtr.AddOption() or a ManagedComboBoxString wrapper instead.
