Map does’t load in reusable block

This map plugin is really great and a real pleasure to use!

I ran into an issue though: when embedding the map in a reusable block, the map show correctly in the editor, but doesn’t show at all in the page.

The <div class="ootb-openstreetmap--map" [...]></div> is in the HTML code, and there is no error in the console.
But the JS script seems to not be loaded (it doesn’t appear in the network tab in dev tools).

If I add another map on the page (not inside a reusable block), the script is correctly loaded and the two maps show correctly.
