Issue

I've been experiencing an issue with poetry for projects that have compiled extension modules. When installing with poetry install, the package is not installed in editable mode. This does not happen with projects that do not contain extension modules, and does not occur for poetry 1.5.1. I took a look through the changelog for 1.6.0 and found this relevant comment by Teagum in PR #7975 , but I didn't see any follow up or issues that captured this.
