"Follow" may create a self-intersecting area

How to reproduce the issue?

1. Create a simple area, say a triangular one (the top one on the screenshot)
2. Start creating another area nearby; snap its 2nd and 3rd vertices to the first area
3. Hit [F] several times to "follow" the first area, i.e. create new common vertices. They go around and around the first area, effectively doing a "plastic wrap".
4. Hit [Esc] to finish the second area. It succeeds.

Now, you've just created an odd, self-intersecting area that can be tagged and committed without a warning.

iD should detect this form of self-intersecting area and prevent executing step (3) or, at minimum, step (4) . Actually, it does complain if I want to complete the area against the topmost vertex, but not in the situation on the screenshot.
