Steps to reproduce
Zoom into a completed item with uncompleted children
Children are not greyed out.
Children are greyed out even though they are not completed.
The point of greying out completed items’s descendants was visual clarity. When zoomed into a completed item, no visual information is added by greying out children since all the children would be greyed out. In fact, greying out everything is a hindrance, making it harder to work with the children.
Completing archived or unimportant items and occasionally zooming into them to work on them is a common workflow for me and others I’d imagine, and it requires the chance mentioned in this bug
