[ML] Anomalies table inconsistent with swimlane selection after changing swimlane limit

[peteharverson]

If a cell is selected in one of swimlanes in the Anomaly Explorer, and a change is then made to the swimlane 'limit' control, the table displays anomalies over the full dashboard time range, rather than the cell which is marked as selected

e.g. after changing the 'limit' control from 10 to 5, the swimlanes indicate a selection from 16:00 to 23:59 on November 3rd, but the table is showing anomalies over all time.

Either the selection should be cleared after changing the limit, or the table should only show anomalies for the selected swimlane cell.
