sometimes sourcemaps detected but not work on chrome canary

Reported by liuhao...@gmail.com, Oct 19 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce the problem:
1. Use webpack to build some Typescript file with sourcemap
2. Use js file bundled by webpack in chrome canary

What is the expected behavior?
sourcemaps works.

What went wrong?
I see message: sourcemaps detected.

accutally, sourcemaps does not work on chrome canary(version 63 and 64).
but it works always on chrome stable(version 61).

Did this work before? Yes maybe 61 or 62

Chrome version: 64.0.3243.0  Channel: n/a

Here is change log between 64.0.3242.0 and 64.0.3244.0:
https://chromium.googlesource.com/chromium/src/+log/64.0.3243.0..64.0.3244.0?pretty=fuller&n=10000
It doesn't look like anything DevTools source map related was landed so if your can provide more details to repro this issue I would try to reproduce it on both versions and try to bisect the change which fixed bug otherwise I'll close this issue and feel free to open another one if bug appears again.
