In a SplitView, cursor look is not reset after hovering above a handle

In a GUI application using the example QML found on the SplitView docs page, when a handle is hovered, the cursor look is set correctly to "double arrow", but afterwards is not reset back to its normal look.

There's no way to fix it, apart from closing the application.

Tested both on Firefox 82 and Chrome 86, on Ubuntu 20.04

I attached a screenshot showing the issue
