Description of problem: When running yarn run dev, any updates to the code cause the following error messages on the command line, as well as on the UI of OpenShift: WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.6b84b2fcf514c70faeb2.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.c96f6392f57648b732df.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.a2cc99bf07991a527fe0.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.ddc1cc802dfb73589528.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.fe3a9ffe8f185357842b.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.3378bc3bf3c652e8733d.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.0cfe74c2f4ee7c361b3f.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.159bf3eafa8a73cd185a.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.91cfc2c690a339ee0bb4.css.map WARNING in Conflict: Multiple assets emit different content to the same filename app-bundle.172facb356843f1e312d.css.map It makes it very difficult to develop since I have to restart yarn run dev whenever these messages appear. Version-Release number of selected component (if applicable): 4.10 How reproducible: Always Steps to Reproduce: 1. Run yarn run dev 2. Make a code change Actual results: Error messages in command line and UI Expected results: No error messages Additional info: Jon Jackson said it seems to be an issue with the .css.map files generated by mini-css-extract-plugin.
