MountedData does not properly being updated after rerendering.

**Problem**

`MountedData` is the structure that provides `get_client_rect` function to get position and size of the element.
It can be stored somewhere by cloning `Rc` from the `onmounted` callback.
The `Rc` should point exact same element or the `onmounted` callback should be called after the re-render

**Steps To Reproduce**

- Use onmounted and store MountedData somewhere else.
- Try re-render the element
- Call `MountedData::get_clinet_rect()` function. It will cause panic.

**Expected behavior**

The stored `Rc` should return values properly. or the callback registered on the `onmounted` should called after re-rendering.

**Environment:**
- Dioxus version: `0.5.1`
- Rust version: `1.77.2`
- OS info: `Windows`
- App platform: `Desktop`
