Reviving this old thread to say this is still occurring. It’s easily reproduced in a new file:
- Create a few objects.
- Isolate one of them.
- Unisolate
- hit undo to undo step 3
- Try to unisolate again
- “No items hidden”
The pain here is that now you’ve accidentally added a bunch of items to your hidden items. You can’t separate the hidden items from the items that were only hidden because you isolated them in step 2. So, you have to go into your hidden items and unhide everything except the items that you really wanted hidden.
