Please also consider handling the root/trunk color here:

should become something like:

        if(isRoot && fillColor === trace.root.color) {
            opacity = 100;
            lineColor = 'rgba(0,0,0,0)';
            lineWidth = 0;
        } else {

Thanks.

Then please add root/trunk color equal yellow to all the traces of the following: mocks:
https://github.com/plotly/plotly.js/blob/master/test/image/mocks/treemap_textposition.json
https://github.com/plotly/plotly.js/blob/master/test/image/mocks/sunburst_inside-text-orientation_clock

to regenerate the new baseline:
once

npm run docker -- run 

then

npm run baseline treemap_textposition sunburst_inside-text-orientation_clock

More info: https://github.com/plotly/plotly.js/blob/master/CONTRIBUTING.md#image-pixel-comparison-tests

Also if you had difficulty making these baselines; you could give us (as maintainers) the permission to push to your branch so that I could generate the baselines for you!
see https://github.com/plotly/plotly.js/blob/master/.github/PULL_REQUEST_TEMPLATE.md

Thanks.

I like this new attribute in principle :)

@thierryVergult we are planning next plotly.js minor (possibly next week) to include new features like this one.
Would you please addressing the following comments?

Thanks.

I'm pretty busy these days. Not sure I will find some time this week for further follow up.

Thanks for the info.

And I'll open up a PR shortly to address my comment and add tests.
