Source map is not visible at Chrome network tab

Question

Before Google Chrome update I saw source map files at Chrome Devtools on Network tab. Now, after update to version 43.0.2357.134 m I don't see them.

Maybe my code is wrong? Or it's done intentionally to hide those source maps?

Did you open an issue for this? – Rafael Maiolla Oct 14 '15 at 18:06 — Rafael Maiolla, Oct 14 '15 at 18:06
No. If you wish you can do that. – Viacheslav Kondratiuk Oct 14 '15 at 18:37 — Viacheslav Kondratiuk, Oct 14 '15 at 18:37

There is a way to get this information by searching for "map" in

chrome://net-internals/#events

This was a side-effect of fixing bug 362913 which was a feature request being tracked in issue 465032.

If you have a need for seeing the map files then please file a new issue for it and explain the use-case for why you need it.

If the source map worked, in dev tools:

The name of the source map file is at the end of your minified source file:
When you open a source file ([Cmd + O] or [Cmd + P]) by definition that means that it could be mapped, and you can see from which file at the bottom of the source editor:
