VS 15.5.0, ReSharper 2017.3 EAP 8 (latest version of both)
- clearing ReSharper cache via options
- clearing ReSharper cache manually
- full fresh git clone of solution
- many OS reboots
- uninstall / reinstall ReSharper EAP 8
Nothing above has any effect; Code cleanup always inserts extra lines into HTML spaces.
This started happening after I upgraded to EAP 8.
