Multiple copies of the same button don't work.

[ekmett]

If you instantiate the same "Button" control multiple times, only one of them fires (it seems this is only the latest one placed?)

e.g. I have a circuit with controls inside of it for embedded test that uses UP and DOWN to take the circuit offline and run randomized testing.

This works fine in isolation, but if I go to instantiate it multiple times for a composite test bench, now only the latest one eats the event.

This means I have to pull all the keyboard control into a central location making a mess of top level wiring.

You can see this just by making a small circuit with several UP buttons linked directly to LEDs for indication.
