Running Webstorm 2021.2.1. I have 2 identical projects (we're in the process of forking). Debugging works as expected in the original project, but not in the fork (the exact same code). The run configurations are identical down to the `workplace.xml` file. I'm using `yarn serve` to run in debug development mode. I can see the output in the Console pane, but the Debugger is not stopping at breakpoints and shows no variables. Am I missing some obscure setting or something? Any suggestions?
