In Blender 3.2 with many exactly duplicated vertices, the Weld modifier does nothing.

As the vertices are exact duplicates, the final resulting mesh should have one vertex. In this example there are 100.

NOTE: This report was made as part of investigating D15220. This might not technically be a bug, as the tooltip reads "Limit below which to merge vertices", however I think we may be worth using <= instead of < comparison so it's possible to merge only exact duplicates.

SelectSimilar.blend
From the menu, choose `Menu > Select > Select Similar > Area"

Bug: Selection remains unchanged.

Expected: Selection extended to all 16 squares.
