1603723 - Script inside of iframe is not displayed in Sources pane

Status: NEW

(DevTools :: Debugger, defect, P3)

Attachment: Chrome

When a script is inside an iframe, is not displayed in the source tree (Sources pane). This makes impossible to evaluate such code.

Example is JSBin:

• Open http://jsbin.com/lohexapude/edit?html,js,output
• The JSBin output pane is displayed in an iframe which has a second iframe as child where the bin code (added to JavaScript pane) lives inside a script tag. This code is not listed in source tree becoming unreachable

For reference, Chrome list this code in their source tree in a separated item:

<proxy> (runner) > JS Bin Output (about:blank) > (no domain) > lohexapude.js

Tested in Fx 73

:Honza, if you think that's a regression, then could you try to find a regression range in using for example mozregression?

@Jason, do you think this is a regression?

So, when i checked a simpler page -- https://dbg-iframe.glitch.me/ it looked like Nightly has all of the JS sources that chrome has, but chrome does a good job of grouping them below the Iframe, which is nice. Especially in a fission context.
