Interactions with QGIS virtual layer cause QGIS to hang.

[EnronEvolved]

What is the bug or the crash?

When attempting to export a virtual layer, filtering a layer retrieved from an ArcGIS REST feature server by intersection with local geometry, QGIS fails to bring up the export menu, and locks up completely. A similar hang occurs when attempting to access the layer properties.

My desktop environment informs me that the application is not responding, and I am left with no choice but to force-quit the application.

Steps to reproduce the issue

1. Add this English Heritage feature server as an ArcGIS REST Server, and add the "Detailed Mapping" and "Project Area" layers to the project.
2. Import these two layers into a new virtual layer, and use the following query:

   SELECT pts.*
   FROM 'Detailed Mapping' AS pts,
    'Project Area' AS plg
   WHERE plg.fid = 37 
     AND ST_Intersects(pts.geometry, plg.geometry);

3. After creating the layer, attempt one of the following actions on the layer through its right-click menu: a. "Export → Save features as..." b. Viewing "Properties..."
4. Observe non-responsiveness of QGIS.

Further testing, having downloaded the ArcGIS layer in question, has established that the issues persist even when the layer is downloaded.
