[BUG]: selectedpoints for curvenumber > 0 invisible when using scattergl

Description

When setting selectedpoints on a scattergl trace for curvenumbers > 0, the markers disappear - for curvenumber 0 it works as expected.

Screenshots/Video

Works as expected:
var curveNumber = 0;
var selected = [0, 1, 2];

Selected markers disappear:
var curveNumber = 1;
var selected = [0, 1, 2];

Steps to reproduce

Please switch between curveNumber = 0 and curveNumber = 1

Error messages in the browser console:

I posted the issue here first. However, this seems to be a plotly.js bug.
This might be related.

Inizia dalla riproduzione CodePen collegata e confronta il comportamento di scattergl per curveNumber 0 e 1 quando selectedpoints è impostato. Analizza gli errori di disegno WebGL riportati nella console del browser e il possibile issue correlato #7271. Il lavoro è completato quando i marker selezionati rimangono visibili per i numeri di curva diversi da zero senza gli errori del buffer segnalati.
