@jmakowski1123 @sdaitzman @edschema This is ready for AC testing on the sandbox

We think there might be some race conditions between the database and the search index updates that affect this issue, so when you're testing, could you please take careful note when you delete a Component that's used in one or more Units, whether the component counts on the Unit card(s) are updated correctly? Thank you!

This seems to be working correctly. I put one text block in three units. I deleted the text block from within one unit. The text block was deleted from all three units it was in, and the counts on the tiles were updated.

When a component is deleted from within a unit, I think we should expand the warning message to also say: If this component has been used in other units, it will also be deleted from those units.

Not a blocker.
