Issue/Introduction

With Auto Expand enabled on an expandable Task or OBS tree backed by a large task hierarchy (e.g. > 2,000 tasks), the tree grid does not show every node. Some rows never appear (not rendered or not loaded), so the tree does not match the full hierarchy in the data source.

Steps to reproduce

1. Create or use a project with a task hierarchy larger than ~2,000 tasks.
2. Configure the widget to use a Task tree or OBS tree.
3. In table properties, turn Auto Expand on.
4. Open the page and observe the tree (scroll through the full depth/breadth as needed).

Expected Results: Pagination (and related loading) behaves correctly, all nodes from the hierarchy should be visible in the grid, consistent with the underlying data.

Actual Results: The grid is incomplete—one or more nodes are missing (not displayed or not loaded), so the visible tree does not represent the full resultset.

Workaround: Apply a filter; with a filter in place, all rows (nodes) appear as expected.
