Bugzilla

This was seen during a benchmarking study we did recently. There were a few participants who faced this issue. 
Essentially, they deleted their history either from the history tab or from data management in settings. 

There were 2 bugs seen. 

1.) See attached video. 
Steps of what happened(unable to reproduce). 
- The user deletes everything from the history tab.
- The history tab shows an empty page.
- User goes to reading list or bookmarks or any other tabs. 
- Comes back to the history tab and still sees 3 tabs in history, but in the recent session post deletion, they haven't accessed or opened any tabs. 
- They delete it again.
- Now they see 1 tab in history without accessing any new tabs.
- 3rd time is the charm, this deletes everything successfully.
