Checking the following settings helps avoid miscellaneous issues:
  * Settings -> Editor -> General -> Remove trailing spaces on: Modified lines
  * Settings -> Editor -> General -> Ensure every saved file ends with a line break
  * Settings -> Editor -> General -> Auto Import -> Optimize imports on the fly (for both Kotlin\
