Closed path is not recognized as face

[pasbi]

Describe the bug Sometimes faces (closed paths) are not recognized correctly.

To Reproduce Create a path like on this image:

Expected behavior The closed area should be recognized as a face and filed with the blue brush.

Additional context It seems like the problem is caused by the two consecutive 3-joints. If the 3-joint is separated by another 2-joint (or ordinary path point), the face recognition works.
