Stop EditorBaseControl from letting PointerPressed events bubbling up...

[minesworld]

by adding e.Handled(true);

void EditorBaseControl::OnPointerPressed(DUX::Input::PointerRoutedEventArgs const &e)
{
	__super::OnPointerPressed(e);

	Focus(FocusState::Pointer);

	// The focus state seems to get confused if the following code is placed in ImageTarget_PointerPressed.
	// OnPointerReleased is the same for symmetry. ImageTarget_PointerMoved is there to show correct cursor
	// when moving the cursor over the scrollbar (UWP).

	if (auto imageTarget{ GetTemplateChild(L"ImageTarget").try_as<UIElement>() }) // Todo: Store this
	{
		auto point{ e.GetCurrentPoint(imageTarget) };
