Label clips when calling render function prop of TextInput component in outline mode

### Current behaviour

The label of TextInput component clips in outline mode when I call the render function prop. I am calling the render prop so as to render my Custom input, in this case a dropdown select input. Space is sufficient so it should not clip the label. Is the their a way to work around it ?

### Expected behaviour

Should not clip the label

首先，使用提供的 React Native、React Native Paper 和 Expo 版本，复现 issue 中描述的使用 render prop 和自定义下拉菜单的 TextInput outline-mode 情况。比较带有和不带有自定义 input 时渲染出的 label；当有足够空间时 label 不再被裁剪，即表示完成。
