After profiling, delay seems to be caused by the sorting by 'lastVisit'
of the HistoryDomainListModel. It should be possible to remove it by
either sorting when items are inserted in that model or just by
leveraging the fact that HistoryModel loads history entries from the
SQLite database with "ORDER BY lastVisit DESC".

Title:
History view is slow to load with a large amount of records
Status in webbrowser-app package in Ubuntu:
In Progress
Bug description:
What happened:
The history view takes many seconds (between 8-9 seconds on mako) to load
when it has a large number of records (I currently have 4640 records).
What I expected to happen:
For the view to load in a reasonable amount of time, by either only showing
recent entries or trimming the db. Other browsers only show the history for
today/yesterday in the initial view and then have buttons to show older history.
Note: that when testing multiple windows, if one window is looking at
the history view and the other navigates to page it blocks the UI for
a few seconds as the history view is being updated.
