Issue: Sticky text disappears after summoning and releasing

After a collaborative brainstorming session, I summoned participants to look at specific stickies, and after releasing them, the text from all of one participants' stickies disappeared. You can still see the text via the activity log, but it cannot be restored because it was not deleted. This may be a bug (?). Regardless, it can disrupt the flow of collaboration and make individual participants feel their voice is not heard/seen/valued. Can this be fixed, or is there any setting/way to restore this text without having to physically re-type what's in the activity log?
