[BUG]: Clusters within scattermaps fail to display with at least one custom style

Description

I am attempting to add clusters to a Plotly.js scattermap that uses a custom style ("https://tiles.openfreemap.org/styles/bright") for the map's style argument. When clusters are disabled, the map appears as expected:

Meanwhile, when clusters are enabled, only points not grouped into a cluster (i.e. Honolulu) are visible:

When I checked my console, I saw the following error:

Basically, the clusters appear to require a specific font (Open Sans Regular) for the cluster labels, but this font isn't available within openfreemap's server. (In other words, Plotly is requesting font information from https://tiles.openfreemap.org/fonts/Open%20Sans%20Regular/0-255.pbf , but that page shows a 404 Not Found message.)

One option would of course be for OpenFreeMap to add this font to their server, but it would be preferable to modify the library, if possible, to not require this particular font. (If there's already an option to do so, please let me know.) If that wouldn't be possible, perhaps the library could be updated to show clusters but not labels? That would still be a major improvement.

Thank you in advance for your assistance!

Steps to reproduce

Here is a Codepen that demonstrates this functionality. Note that, if you zoom in enough, the underlying clusters' dots will begin to appear. Thus, the issue is with clusters rather than their data.

Notes

One of my reasons for using this custom library is that, based on my correspondence with Carto, our organization may need to pay a substantial amount of money to use Carto's own tiles for our work. This is not the case with OpenFreeMap, which is why I strongly prefer using them in place of Carto. If I'm misunderstanding this licensing situation, just let me know.

有効化された scattermap クラスターと OpenFreeMap のカスタムスタイルを使用して、リンクされた CodePen で失敗を再現します。scattermap クラスターのレンダリングエントリポイントと、レポートに示されているフォントリクエストを調査します。そのスタイルでクラスター化されたポイントが利用できないフォントを必要とせずにレンダリングされるか、サポートされる制限が明確に確立されれば完了です。
