customdata is missing in clickData for Scattergl objects

Describe your context
I've made a dash application that presents some data from an SQLite database both in a graph and an AG Grid table. I'm using scattergl to create a figure with scattergl traces. Clicking a point on the scattergl traces fires a dash callback that should highlight the relevant data in the table. The mapping of the data between the figure and the table relies on the customdata variable of the scattergl class, and that the clickData passed by the click event carries with it the customdata data. This has been working until I recently upgraded my environment.

Describe the bug

The bug is the same as that described in https://github.com/plotly/dash/issues/2493, except that I'm experiencing this with Scattergl objects (added to a plotly.graph_objs._figure object with add_traces). Note that this worked just fine before I recreated my environment (and updated many of my packages). Unfortunately I don't have the package list of the old environment.

Expected behavior

I expected the data in the customdata variable of the Scattergl trace to be present in the clickData object I receive in my figure callback, just like before I upgraded my environment.

Screenshots of actual behaviour
Firstly showing created Scattergl objects containing data in its customdata variable.

Secondly showing the click_data dict received in my dash callback after clicking a point on the scatter graph, which does not contain 'customdata'.

Beginne mit dem Dash-Figure-Callback und einem Scattergl-Trace mit customdata und reproduziere das fehlende Feld in der gemeldeten Dash-2.18.2-Umgebung. Vergleiche die empfangenen clickData mit den erwarteten Trace-Daten; das Issue ist abgeschlossen, wenn customdata für angeklickte Scattergl-Punkte vorhanden ist.
