WASM: RuntimeError: memory access out of bounds [QCursor]

This was raised in 6.5.1 can it be fixed in the 6.5 branch if possible?

It makes QML/WASM in the 6.5 LTS branch unusable

During the running of a WASM QML example app you get the following crash:

RuntimeError: memory access out of bounds

Steps to produce:

Build the project: ./Examples/Qt-6.5.1/quickcontrols/chattutorial/chapter3/chapter3.pro
Using the WASM multithread version of Qt (I was building and testing on macOS).

Then do the following in the browser app:

1. Select any person from the contacts list
2. Press the top left 'Back' button (in the app not the browser back button)

You then get the error:

Qt for WebAssembly: chapter3
Application exit (RuntimeError: memory access out of bounds)

with the stack track in the console:
