WASM: QNetworkReply, after calling abort QNetworkReply->error() is not OperationCanceledError

I applied the fix from https://bugreports.qt.io/browse/QTBUG-72516 to my Qt 5.12.0 source manually(Without it finished is not emitted).

The attached example makes an http request to "http://urlecho.appspot.com:81/echo" on clicking "Go" with a 3 seconds timeout that calls abort.
Since the request can not work for port 81 the timeout should always trigger.
The signal finished is emitted but QNetworkReply::error() does not return the expected OperationCanceledError.
 

In the following image you can see what happens in the attached example on Linux:

And Webassembly:

I fixed it for myself like this:

// qtbase/src/network/access/qnetworkreplywasmimpl.cpp
void QNetworkReplyWasmImpl::abort()
{
	Q_D(const QNetworkReplyWasmImpl);
	d->doAbort();	
	setError( QNetworkReply::OperationCanceledError, "Operation canceled" ); // Fixed it for me
    close();
}
