            Bug ID: 244814
           Summary: Web Inspector: incorrect lines when using esbuild
                    sourcemaps
           Product: WebKit
           Version: Safari 15
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org

I have a minimal example app which could be built with either Rollup (using npm run build:rollup) or esbuild (using npm run build:esbuild).
https://github.com/chicoxyzzy/esbuild-sourcemaps-safari

When I build the app with Rollup and then run the server (npm start), I can see that line of console.error points to correct line (line 7) in Safari Web Inspector
When I build the app with esbuild, it points to the wrong line (the last line of the module — line 15) in Safari Web Inspector

The line is correct for Chrome and Firefox
