DevTool_Page Extension not running when opening dev tools on site

[Jonathon Black]

Currently experiencing an issue where a custom dev tool extension is added to the tabs available in the dev tools window, once the dev tools are opened. This works fine when opening when on Google but when I access another website such as Kenzo and go to open the dev tools it looks like this action isn't picked up and the devtools_page (manifest v2 ref) doesn't seem to run as expected when the page opens.

Has anyone experienced anything similar or found a work around when a custom devtools_page fails to open on selected website pages? (I do give the extension <all_urls> permission and has been working in the past) - seems strange that it fails on a given website but works on regular Google pages

It's a recent bug in Chrome, which was reported by dozens of extension authors in many reports, but due to its randomness it got confirmed only yesterday in https://crbug.com/1311690, so no one yet knows what causes it. Maybe you can add your test case there.
