Description
### Problem Description
Before Revit 2025 none of the elements got exported that were hidden by turning off the subcategory their entire geometry belonged to on the view that was used for export, so we had consistent results. Since Revit 2025 this visibility setting seems to be ignored, and only the export mapping is considered, which results in inconsistent behaviour. Is this an intended change, and if so, where it is documented?
### Revit Version
2025.4.x
### IFC for Revit Addon Version
25.4.0
### Windows Version

Contributor guide
Research direction
Start by reproducing the export with Revit 2025.4.x and IFC for Revit 25.4.0, using a source view whose subcategory is hidden, then compare the result with the export mapping. Done means determining whether the changed visibility behavior is intentional and documenting the confirmed behavior or required fix.
