Changing 'done' task(entity) status back to 'open' should remove 'completion date'

I marked some tasks back to ‘open’ (as some rogue Zapier zaps triggered them to complete). However what I didn’t anticipate is that the original ‘completion date’ remains in the ‘completion date’ field. I didn’t realise this until later when some filters weren’t working properly (due to the tasks being ‘open’ but with a ‘completion date’). From my perspective Fibery should remove the completion date if I change the entity status back from ‘done’ to something else.
