@Lexachoc thanks for the bug and fix! In the future, could you please add a description and list of changes? Your bug report contains a good deal of information, but it would be helpful to have some of that in the PR. I always appreciate a one line fix. I added one small suggestion and I wrote a test for this situation (based on your Pen). Good work!
no need to coerce binNumber from integer to string as suggested Co-authored-by: Cameron DeCoster <cameron.decoster@gmail.com>

This PR fixes #7502
Description
Fixes a bug where
hovermode:'x'(this PR also works for other hovermodes like'x unified','y','y unified') on histogram would not trigger hover events over consecutive zero-count bins.Previously, hovering over empty bins would keep reporting the first empty binNumber, causing stale hover data and breaking expected behavior.
Changes
Ensure hover events fire consistently across all empty bins. Correctly report the actual binNumber (and trigger hover event).
