Plot legends in Time Strip don't show values on hover

Summary

When a plot in a Time Strip has the cursor over it, it doesn't respond to the mouseover event and show a current value in the legend, but should.

Expected vs Current Behavior

Mouseover events in the plot in a Time Strip should behave as they do in native plot views.

Steps to Reproduce

1. Put a plot view in a Time Strip.

Additional Information

After a brief investigation, this doesn't appear to be a CSS-related issue, like setting pointer-events: none.
