Changing a powered Command block from impulse/chain mode to repeat mode doesn't trigger it until repowering

I don't know whether or not this is intended to be this way, but i'll report it anyways just to be sure.

When you place an impulse command block and put a command in it and then activate it, it works. But if you keep it powered and you change it from impulse to repeat, it wont trigger. It will trigger once it is turned off and turned on again.

_{Additional description from KingSupernova:}
To clarify the description a bit, this occurs both if the block is set to "Needs Redstone" and is receiving power, and also if it's set to "Always Active". It's also worth noting that this is not fixed by updating the block, the setting must actually be changed back to Needs Redstone, then back to Always Active.

This bug also occurs with impulse mode. Set it to Chain and Always Active and type in a command. Then change it to impulse. The command will not be run until it is changed to and from Needs Redstone.
