Impossible to use the node tool together with an LPE'd path (CanvasItems)
Summary:
This is related to inkscape#1809 (closed), in that the same CanvasItems rewrite is responsible for introducing this bug. @Tavmjong has told me that this bug is caused by inkscape@22628fed.
It is impossible to use the node tool to edit a path that has an LPE on it.
Steps to reproduce:
- Open the attached file
- Open the node tool
- Select the only path in the file

I should have been able to use the node tool to edit the underlying path, as it worked in versions prior to the CanvasItems rewrite.
