Description
Button in a batch group doesn't update the batch group after its state changes - for example if I press a batched button, its visual representation won't change. I have to manually listen for "pressedstart" and "pressedend" and mark the batch group as dirty.

Research direction

Trace how a button state change affects its visual representation and batch dirtiness. Done means pressing or releasing a batched button updates the batch group automatically without requiring manual event listeners.
