[Bug]: LassoComponent deletion crash when used with touch. With mouse it's fine [develop, 8.0.1]

[onar3d]

Detailed steps on how to reproduce the bug

in .h file:
std::unique_ptr<LassoComponent<TimelinesDraggable*>> m_LassoComponent;

in .cpp file:
::mouseDown(const MouseEvent& e) {
m_LassoComponent = std::make_unique<LassoComponent<TimelinesDraggable*>>();
addChildComponent(m_LassoComponent.get());
m_LassoComponent->beginLasso(e, this);
}

::mouseDrag(const MouseEvent& e) {
m_LassoComponent->dragLasso(e);
}

::mouseUp(const MouseEvent& e) {
m_LassoComponent->endLasso();
removeChildComponent(m_LassoComponent.get());
m_LassoComponent.release();
}

The above works fine when interacting with the mouse.

But when selecting with a finger on a (multi) touch screen (iPad Pro over Duet), and then closing the view that contained the hosting component, there's a crash with the stacktrace shared.

This happens with develop, Juce 8.0.1, and the latest version 7 too i think (I tested with an older release build that used Juce 7).

I haven't spent the time to make a minimal demonstration of this, and there's no lasso in the Juce demo that I know of. If I'm missing something do point me to the demo with a lasso and I will try to reproduce the behavior there too.

What is the expected behavior?

That it won't crash.
