How to reproduce the issue?

I think the screenshot is self-explaining:

Screenshot(s) or anything else?

Seems intersection is detected if and only if two lines intersects. But in this case segments have common nodes and this cause no lines intersection. But buildings are definitely intersected!

Maproulette challenge detects it, iD doesn't

As a side note, I had assumed this behaviour was intentional when I created #10120. If this is indeed a bug, then #10120 will need reworking

Hm, #10120 has different shape: two squares with a common edge

[k-yle]

yeah #10120 is a different arrangement, but my "fix" for that issue assumes that your screenshot is a valid situation.

Anyway, I'm following this thread now, so I can update #10120 depending on what happens here
