What happened?
I just wanted to raise awareness that the current code base (post 0.0.77 release) contains a regression bug:
The following constellation:
- IfcWall container (no geometry)
- IfcBuildingElementPart wall layers (geometry)
- IfcOpeningElement (voids IfcWall)
leads to a stall during geometry extraction of IfcBuildingElementPart. StreamMeshes basically stops to respond without error which usually halts the extraction process.
I could reproduce this with several files and included a minimal example file. The example also stalls https://thatopen.github.io/engine_web-ifc/demo/
The files all work in 0.0.77, so this must be caused by a recent change.
In case this is a known "work-in-progress" issue of the unreleased build, feel free to delete this issue.
Sample file expected output:

Version
0.0.78 (unreleased, not a production issue)
What browsers are you seeing the problem on?
Chrome
Relevant log output
Anything else?
