Description

### Current behaviour
A multiline `TextInput` element expands to adapt to text content on mobile, but it doesn't on web. Instead a scrollbar appears inside the `textarea`

### Expected behaviour

`TextInput` expands on web to adapt to text length, like it does on mobile. This is expected under the material guidelines: https://material.io/archive/guidelines/components/text-fields.html#text-fields-field-types

### What have you tried

Adapting the height through `onContentSizeChange`, however the textarea never shrinks in size when deleting text:
```javascript
const [height, setHeight] = useState(undefined)
{
setHeight(event.nativeEvent.contentSize.height)
}}
style={{ height }}
/>
```

### Your Environment

| react-native | 0.64.3
| react-native-paper | 4.11.2
