Thinking about this PR, it looks like a `change` that could possibly include in v3.0.0. @gvwilson @my-tien Would you please merge master into this branch so that the tests pass?...

> @archmoj: I opened #7247 and rebased the branch on the latest master (I don't have access to my-tien's original branch). If you want, you can merge the new PR...

This issue would be resolved by #7006.

You could use `v1hovermode` or `hovercompare`, `hoverclosest`, `togglehover` and `togglespikelines` in `config` similar to [this codepen](https://codepen.io/MojtabaSamimi/pen/YzVbzox?editors=0010). Please see #5654 for more info. In addition you could use `layout.modebar.add`. Please see...

Right now time zone is not set to Alaska when generating the baselines (UTC is used). However if/when set 6 mocks render differently. See `diff-*` here: https://app.circleci.com/pipelines/github/plotly/plotly.js/5057/workflows/960e81f3-b5ff-4ee8-9b3b-41b5b7cce5d9/jobs/128237/artifacts

Another observation is that by setting the timezone to `Europe/Berlin` some jasmine tests fail here: https://app.circleci.com/pipelines/github/plotly/plotly.js/5058/workflows/9afde51b-d32b-483f-9e30-56899bc50f59/jobs/128248

@alexcjohnson thanks for the clarification. This is still rather confusing. With different marker sizes, how one could force a graph not to have any transparency?

> marker.opacity = 1 ? That works for me!

Case of `legend.grouporientation: 'h'` when `legend.orientation: 'h'` is out of scope of this issue. Right?
