Rename a model, click Done
Click "Rename Items" again
The model option is selected but the rest of the dialog does not appear.
Edit 2/15: Found another bug which might have the same root cause:
Open model library in firefox and click create model
Enter a new model name and submit form (new model should open as expected)
Return to the tab with the model library
Click create model again. The old model name is still present in the form, and the form submit button no longer works, even if you change model names or refresh the page. Create model is effectively broken as long as you keep working in the same tab.
