Issue:
When adding a function to GUI.Rectangle.onPointerUpObservable the event is not firing when using chrome on desktop until the mouse leaves the canvas.
Example:

It work’s fine on mobile chrome.
Bug is present on: Windows 10 x64, Google Chrome 79.0.3945.117 x64,
Bug is not present on: OnePlus 5T, Google Chrome App 79.0.3945.116
Btw. I’ts very irritating that such a fundamental basic feature as drag and drop is not part of the GUI framework
