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.

Inizia eseguendo il Basic Sunburst Example dalla documentazione di Plotly JavaScript e confronta le transizioni delle etichette con il video allegato. Leggi l'Icicle Plot Issue collegato per il comportamento correlato delle transizioni. Il lavoro è completato quando etichette come Awan, Abel e Cain rimangono visibili e passano alle posizioni e alla scala di destinazione senza scomparire.
