Notebook page at 400% cannot see the notebook title, the language of the notebook, the jupyter link to go back, or the help dropdown. In addition the "Not Trusted" block is partially cut off when appearing (also can't edit the title of the notebook but revealing it will most likely fix this).

**Issue Area # 2**
- **Expectation**: Can the page be zoomed to 400% zoom in a 1280px wide display without requiring two scroll bars? (WCAG Criteria 1.4.10 (AA)).
- **Observed**:
- Notebook page at 400% magnification cannot see the notebook title, the language of the notebook, the jupyter link to go back, or the help dropdown. In addition the "Not Trusted" block is partially cut off when appearing (also can't edit the title of the notebook but revealing it will most likely fix this).

Reproduce the notebook page at 400% zoom on a 1280px-wide display and inspect the page layout. Done means the notebook title, language, Jupyter back link, help dropdown, and full “Not Trusted” block are visible without requiring two scroll bars, and the title can be edited.
