Show analysis table highlight above quality coding layer (#304)

When hovering over rows in the analysis tab, highlighted sections for
the route could only be seen on the regular route, but not when any of
the color-coded route visualisations were selected.

Patch based on a similar fix for data table in d33c795200.
