Unexpected grey loading bar appears when refreshing a blank new tab

Steps to reproduce

1. Open the app
2. Go to Settings and set New Tab to Blank Page
3. Create a new tab
4. Either:

#* Pull to refresh the blank page, or #* Force close the app and reopen it

Actual Result:

• A grey horizontal scroll bar appears
• The URL bar is hidden

Expected Result:

• Either nothing should happen, or we should remove pull-to-refresh from the blank page
• The URL bar should always be present on this screen

Notes

• If the issue doesn’t reproduce right away, try restarting Firefox after setting the New Tab to Blank Page, then repeat the steps.

Device & build information

• Device: iPhone 15 + (18.2)
• Build version: v139 (55702)
