2023: Uncaught TypeError: d3.mouse is not a function

2023 and this is still not fixed?
I use D3 `v7.8.3` and `0.7.20`.

```

```

What is going on? :)

As soon as i move by mouse over the chatter chart it throws an error:

PS. In this example https://c3js.org/samples/chart_scatter.html D3 is `v5.8.2` and C3 is `v0.7.20`. And it WORKS OK (no d3.mouse() error).

And I test it via basic HTML code (based on example BUT replacing LATEST versions of D3 and C3 from CDN) on Chrome `v111.0.5563.110 (Official Build) (arm64)` on Mac OS Ventura `v13.2.1` on iMac w M1 CPU.

So why latest C3 is not synchronised with latest D3 v7.x?
