Description
We have come across an issue with scatter plots where the hover labels do not match the value of the x-axis on a (time) period axis. The problem only occurs when setting the layout.scattermode property to "group" and shifting the markers using the xperiodalignment property to "start" or "end".
Here is a codepen which demonstrates this behaviour:

Research direction
Reproduce the mismatch using the linked CodePen, with scattermode set to "group" and xperiodalignment set to "start" or "end" on a time-period axis. Trace the scatter and hover handling for these properties, add a regression test covering the shifted markers, and verify that hover labels match the x-axis values.
