VisualEditor Compatibility Issues with Datatables in Broadtable Format

[YOUR1]

Setup

• SMW version: 4.1.2
• MW version: 1.35.11 (and also on 1.39)
• PHP version: 7.3 (and up wards)
• DB system (MySQL, Blazegraph, etc.) and version: MariaDB (10.5), ES 6.8
• VisualEditor: 0.1.2

Description of the Issue:

We are experiencing a critical issue with VisualEditor when it interacts with the datatables query format in SMW. Specifically, on our closed system, VisualEditor encounters an Out of Memory (OOM) error when attempting to display more than 100 results in a datatable. This issue is consistently reproducible.

Additionally, we observed the same problem on the SMW sandbox environment. In this case, VisualEditor fails to load datatables entirely. While we cannot confirm if this is due to the same OOM error we experience in our system, the symptoms suggest a related or identical issue.

Reproduction Steps:

1. Access the SMW sandbox at Sandbox: Song Test Page.
2. Open VisualEdtior
3. Observe the failure in loading (or presumably an OOM error while error reporting has been enabled).

Expected Behavior:

VisualEditor should be able to load and display datatables of any size without encountering memory issues or failing to load.

Actual Behavior:

VisualEditor experiences an OOM error when loading more than 100 results in a datatable on our deployments. On the SMW sandbox, it fails to load the datatables at all.
