Wipe While Retracting causes issues in vase mode

[TouchMonkey]

Description of the bug

In PrusaSlicer 2.7.2-beta1, enabling Wipe While Retracting causes issues with vase mode. The slicer inserts a wipe at every layer change which causes a gap to appear.

The issue is visible in the preview, but just to clarify, this is not a preview issue. The tool head skips forward instead of moving around in a continuous motion. Disabling WWR resolves the issue with no other setting changes.

The tool head also seems to purge without retracting first, which is causing blobs at every layer change. This occurs even if "Retract on layer change" is enabled.

Project file & How to reproduce

The issue is easy to reproduce using the standard vase-mode extrusion multiplier calibation cube. Attached is one such project.
