Color is lost after the STEP file is loaded

[qingbc777]

Describe the bug

The model in STEP format has its own color, but the color is lost after parsing through occt-import. Strangely enough, after I split the STEP file and imported the split part again, the colors were able to read normally.

To Reproduce

1: Load the entire model, the color is lost
2: Part of the model is loaded and the colors appear normally
Model in attachment
table.zip

Expected behavior

If the model has color, it should be left in its original state.
