Background color style does not work with nested text

[jobpaardekooper]

The following code displays the text with a white background:

<UITextView selectable uiTextView >
    <UITextView selectable uiTextView style={{ backgroundColor: "#ff0000" }} >test 1</UITextView>
    <UITextView selectable uiTextView style={{ backgroundColor: "#00ff00" }} >test 2</UITextView>
</UITextView>

Using a single, non-nested component with a backgroundColor works:

<UITextView selectable uiTextView style={{ backgroundColor: "#ff0000" }} >test 1</UITextView>

Also giving the container a background color works. But I want to give only a part of the text a background. Other styles like color are working as expected. Just seems to be an issue with backgroundColor.
