Description

On Android, the <TextInput>'s placeholder property always renders to multiple lines, whereas on iOS it trails the ending (like ellipsizeMode="trail").

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Create <TextInput> component
2. Set placeholder to anything long

Expected Results

The placeholder should leave dots at the trail, so no line wraps.

Snack, code example, screenshot, or link to a repository:

<TextInput
	style={textInputStyle}
	placeholder={"This is a test placeholder which doesn't ellipzise with trailing dots"}
	placeholderTextColor="gray"
	value=""
/>

Current workaround I can found for now is add maxHeight: <fontsize + padding> to style prop.
