Broken text transitions for sunburst/treemap charts

This issue is described in the Icicle Plot Issue but in the context of an Icicle plot.

Reproducible Example

Check out the Basic Sunburst Example from the docs: https://plotly.com/javascript/sunburst-charts/#basic-sunburst-chart

Describing the Bugs

• At the 3 sec mark, notice that Awan and a few other text labels disappears.
• At the 9 sec mark, notice that Awan, Abel and Cain are already located at their target X and Y, and that the text scales into view.

The reason I'm grouping these text labels together is because I suspect they are related. There are other more Icicle specific bugs I've noticed in https://github.com/plotly/plotly.js/pull/5546#issuecomment-797026819.

まず Plotly JavaScript ドキュメントの Basic Sunburst Example を実行し、ラベルの遷移を添付動画と比較します。関連する遷移動作については、リンクされている Icicle Plot Issue を確認してください。Awan、Abel、Cain などのラベルが表示されたまま、消えることなく目的の位置とスケールへ遷移すれば完了です。
