state for multiple metrics leaderboards is being lost during navigation

[medriscoll]

Describe the bug The multiple metrics state for Explore Overview leaderboards is overridden by navigation to an expanded dimension table.

To Reproduce In the Explore overview:

• I expand a dimension leaderboard that has multiple metrics visible (for example 2 of 5 metrics)
• This expanded dimension table now shows 5 of 5 metrics (as expected)
• When I click "<-- All Dimensions" to return to the Explore overview, it now shows 5 of 5 metrics

Expected behavior My expected behavior is that returning to Explore overview should show my previous state, which is 2 of 5 metrics.
