1264964 - Devtools: Event Popup in Inspector does not use source map to prettify code

Status: NEW

(DevTools :: Inspector, defect, P3)

Description

Attachment: firefox_devtools_event_popup_does_not_handle_source_map.png

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160407164938

Steps to reproduce:

1. Open Devtools
2. Go to a page which uses minified JS with a source map
3. Hover over a DOM node which has an JS event attached
4. Click on the "ev" button to see the event popup


Actual results:

Event popup shows the source code. It is prettified (alignment is correct), but the source map is not used (varialbe names still minified, etc.) See attached screenshot.


Expected results:

Use the source map to show the code. In the Debugger the code ist shown very nicely. But in the inspector's event popup, it seems like the popup does not use source maps.

Inspector bugs triage. Filter on CLIMBING SHOES.
Non breaking, UI only -> P3.

ni? myself to verify the bug.

FWIW right now this popup gets the source text from the JS engine, not from the sources.
