[BUG] Sourcemaps off by 1 line

What happened?

While debugging extensions in Chrome Devtools, the sourcemaps in content scripts are off by one line. I have this experience working on 2 different extensions. In the screenshot, the breakpoint on line 55 actually activates for line 54, and the debug cursor is currently acting on line 55. Is there a fix for this issue?
