After PR #94 I now have wrong line numbers when using eval, but filen ames for every step in the trace:

with cheap-module-source-map I get right line numbers, but no file names for npm dependencies:

on place 6: "NewsStreamListWidget" the error is in line 16. I tried also some other devtools, with the same result.
I tried version 1.4.1 and 1.4.2
