[FEATURE]: Fix Hover Text In Place On Click

[kurt-rhee]

Description

I would like to be able to fix my hover text in place when I click on a set of traces. This would allow me to compare one part of a trace with another part of a trace.

Why should this feature be added?

I have tried fixing information on click with annotations, but the hovertext algorithm is really good with multiple traces to ensure that hovertext never overlaps.
