Dispensers/Droppers not untriggering after power is removed

Hi, I recently had one of my players encounter a bug with AC, where a dropper will not untrigger after power is removed in a certain configuration. I have provided a schematic below that demonstrates this bug.

Schematic: ac_bug.zip

Simply paste the schematic and press the button twice. You will note that the dropper triggers initially as expected, but will not drop any more items after subsequent button presses. This behavior doesn't make any sense and also isn't present in vanilla.

Cheers.

Thanks for the report! I pushed a fix and will publish updates shortly.

The behavior is present in vanilla, but it only happens in certain locations due to the different implementation. The wire on the concrete is powering the dropper through the other concrete (due to quasi-connectivity, a mechanic where droppers, dispensers, pistons and sticky pistons can receive power from anything that would power the block above them), and in this case it's also turning off after the one directly above the dopper, meaning the dropper is still powered when the wire above it turns off, and since the wire on the concrete does not send any block update to the dropper, it stays powered.
