Plotly.react leaves duplicate clippaths

const container = document.createElement('div');
document.body.appendChild(container);
await Plotly.newPlot(container, [], { title: 'abc' });
await Plotly.react(container, [], { title: 'hello' });

The resulting DOM contains multiple copies of the same clippath:

<clippath class="plotclip" id="clipc001dfxyplot">
  <rect height="270" width="540" />
</clippath>
...
<clippath class="plotclip" id="clipc001dfxyplot">
  <rect height="270" width="540" />
</clippath>

This is causing issues for our accessibility tests, which check that IDs are unique within the document, but in some cases the newer clippath is different (but still shares the same ID), so presumably the items which reference it could pick up an old value and therefore render incorrectly after an update.

(using Plotly 2.24.3)

Inizia con la riproduzione minima nell’issue, confronta il DOM dopo Plotly.newPlot e Plotly.react e traccia dove vengono create o mantenute le plotclip clippaths. Il lavoro è completato quando il grafico aggiornato non contiene ID di clippath duplicati e gli elementi fanno riferimento alla clippath prevista dopo l’aggiornamento.
