@astroshim She posted the test failure.
My guess is that the Notebook has only one paragraph, therefore the xpath
is on the last paragraph.
Since we removed the delete element from the last paragraph, the test fail.
The exact failing tests and the error lines:
```
ParagraphActionsIT.testRemoveButton:153
ParagraphActionsIT.testCreateNewButton:86
```
