Dev Tools: Cannot inspect iframe contents

[lemonjuice]

A sample page with an iframe: http://csreis.github.io/tests/cross-site-iframe-simple.html

Right-click anywhere within the grey frame and choose Inspect. DOM elements will appear within the dev panel but only the main page content is visible but iframe content is not available.

In other chromium browsers like Chrome and Opera iframe is accessible and inspecting an element inside an iframe navigates me right to the chosen element within the DOM tree.

Is this a bug? How can I access iframe DOM within the dev tools?

@lemonjuice That's known

[lemonjuice]

Thanks for the info.

The issue is about DevTools can't inspect Subframe processes while Chrome can

Edited: What's your OS?

[lemonjuice]

@lamarca I'm on Windows 10 x64. Indeed, there is a topic about it here. When I changed the "Site isolation trial opt-out" setting to the not recommended value it started working. I may accept the risk and for the time being run Vivaldi this way until it gets fixed.

@lemonjuice Bug is confirmed, not resolved yet.

Some news about this? As a Developer this is an essential feature, so i still must using v1.15.1147.64.
An option to right click the iframe in new Tab would be nice and very helpful.

Ok, still no progress here, so i have to switch to another Browser.

Patiently waiting. Still need to switch to regular chrome if I want to enter an iframe with the inspector.

Developers, it has been a long time and I do not see at least a crutch solution to this problem.

@Gwen-Dragon You might want to update VB-46458 with a note regarding something I just noticed. While I can't inspect the output IFRAMEs on CodePen and JSFiddle, for some reason the output IFRAMEs on JS Bin are inspectable.

@Gwen-Dragon You're welcome, and thank you for adding it. I hope it's helpful in solving the bug.
