PaperProvider breaks styles

### Current behaviour
When trying to make a Dialog, the entire colors of my elements change

### Expected behaviour
No styling should be affected

### How to reproduce?
Just copy and paste the example of the Dialog and place a anywhere

### Preview

### What have you tried so far?
Placing it at different places in the provider

### Your Environment

| software | version
| --------------------- | -------
| ios | x
| android | 13.0
| react-native | 0.76.7
| react-native-paper | 5.13.1
| node | 23.3.0
| npm or yarn | 10.9.0
| expo sdk | 52.0.19

从 issue 中描述的 PaperProvider 和 Dialog 示例开始，使用 react-native-paper 5.13.1、React Native 0.76.7 和 Expo SDK 52。将一个 Text 元素放置在 Dialog 旁边，并比较有无 provider 时它们的颜色，以复现该行为。完成的标准是：可以使用 Dialog，而不会改变其他元素的样式。
