To clarify: Inline code preview in the events panel works and shows the correct handler. Resolving the filename and location works and shows the original location. Clicking the link to the Debugger is what isn't working and send to the wrong file (generated file instead of original) with the correct original location. In the example, the original location of `index.js:13` jumps to the generated file `client.js:13`.
