Tooltip are not created inside the canvas

[aandrieux]

Version

4.2.1-rc1

Steps to reproduce

For a 3D graphic section "grid3D" set tooltip renderMode to "richText" and Implement a "formatter" function

What is expected?

Tooltips should be created inside canvas as the chart

What is actually happening?

Tooltip are not created in the canvas but outside

---

Yet in the documentation it is specified that this option must make the tooltip inside the canvas
https://ecomfe.github.io/echarts-doc/public/en/option.html#tooltip.renderMode
"It can also set to be 'richText' so that the tooltip will be rendered inside Canvas (SVG rich text is not implemented yet)."

Hi. @aandrieux Can you provide a demo for your question?

Hi Ovilia,
Thank you for your interest in my request. It's hard to give you an example live, but I enclose a screenshot and hope that you understand my indications.

You can reproduce the same behavior on this model :
https://ecomfe.github.io/echarts-examples/public/editor.html?c=bar3d-punch-card&gl=1
and add these lines
tooltip: {
renderMode:'richText',
textStyle: {
fontSize: 30
},
}

I expect the tooltip to be created inside the canvas as explained in the documentation "It can also set to be 'richText' so that the tooltip will be rendered inside Canvas" :(

Thank you

I have tried this example, but not found that tooltip is not rendered inside canvas.
