### Problem Description

User-defined property is missing when exporting ramps from Revit.

When exporting from Revit, as shown in the image below, some ramps are properly exported,
while others are experiencing missing user-defined properties.

Research direction

No source file or test is named. Reproduce the export with Test_경사로.zip in Revit 2024.0.x using IFC for Revit 24.x.x, comparing ramps with and without the user-defined property. Done means the affected ramps retain the user-defined property type in the IFC output.
