🖥️ Steps to Reproduce

https://codesandbox.io/p/sandbox/fervent-architecture-6g96p6

1. Select 1 or more rows
   • You must not select the 1st row only
   • Ensure the blue focus outline appears on the row (it sometimes does not in Chromium-based browsers likely due to the iframe, native :focus has same issues)
2. Click "Toggle" button to swap out rows
3. App freezes

Remove isDisabled from all loading rows in code and try again. It does not freeze anymore.

Thanks for catching this, took a little bit but it seems like the root of this issue is with how we try to find a new row to focus if the previously focused row doesn't exist anymore. Since every row is disabled in the new set of items this portion of the code keeps looping. Off the top of my head, we can probably break out of it by simply flagging when it hits the else a second time but it might be worthwhile adding a function to SelectionManager/Collection that informs us if every item in the collection has been disabled via applying isDisabled to each Row/Item
