I can reproduce this on a clean 2.1.7 installation with these steps:

1. Create or edit a Simple product.
2. Add Custom option.
3. Select 'Drop-down' Option Type.
4. Click the 'Add value' button to add an empty row, leave it empty.
5. Select a different Option Type (doesn't matter which).
6. Select 'Drop-down' Option Type again.

Result is a infinite loader and no javascript error message.
