[bug] When a TextInput is inside a Portal, cursor jumps around on edit

[lovegaoshi]

exactly this issue. doesnt just happen to react-native-paper's portal but other kinds of portals too like react-native-portal.

i forgot which issue it was acutally mentioned, but the root cause is I cannot use states directly in the same component wrapped in a portal. it has to be wrapped inside another component to please this cursor flickering problem. however a dialog does need access to the textinput value and this will be resolved via refs, similar to how i was too lazy to lift the state up for addPlaylistButton.

react-native-paper's input as ref does not seem to expose value, this is logging the ref.current object:
{"blur": [Function blur], "clear": [Function clear], "focus": [Function focus], "forceFocus": [Function forceFocus], "isFocused": [Function isFocused], "setNativeProps": [Function setNativeProps]}

so we cant exactly use uncontrolled props here

why cant i just wrap the entire dialog into another component? using ref sounds unnecessarily convoluted and stupid
