Maps with polygons break visual editor

[prudloff-insite]

Setup

• Maps version: 10.1.0
• MW version: 1.39.5
• PHP version: 7.4.33
• SMW version (if applicable): 4.1.2

Issue

We have a template that prints a semantic map containing polygons.
When using the visual editor on a page containing this template, the initial AJAX request to /api.php?action=visualeditor&format=json&paction=parse... fails with this error:

Exception caught: Call to a member function getUserIdentity() on null

This seems to happen because the parser instance used by WikitextParser returns null when calling getOptions() on it.

I tried to create a simple example on the sandbox (https://sandbox.semantic-mediawiki.net/wiki/Test_Map_with_polygons) but could not reproduce the error.
