extruder: problem with shared nodes

[skyper]

What steps will reproduce the problem?

1. Draw two rectified rectangle closed ways with one overlapping segment and two nodes in common.
2. extrude (single align) on side with one shared node of one area to the inside

What is the expected result?

The shared node remains only part of the untouched area and a new shared node is created at the new corner or the opposite considerering ids (new <-> old).

What happens instead?

The shared node remains shared and a new node only connected to the changed area is created.

Please provide any additional information below. Attach a screenshot if possible.

I changed the settings for "ignore-shared-nodes" but it did not change anything.

Have a look at attached example file​.
