[DevTools Bug]: Extension not loading for local files in Electron since 4.27.5

[Bartel-C8]

Website or app

local file (index.html)

Repro steps

Try to load the React Devtools in an Electron app (latest 27.1.2) which uses a local file to load.

Electron now properly supports loading manifest V3 extension, but there is a problem when loading a local file to the main window.
Context: electron/electron#36545 (comment)

Only workaround is to programatically close the application and re-create the window.
On some systems (Windows?) it seems plenty to just load the extension twice, but on my macOS, this does not work..

I traced the commit breaking this is: #26492
So v4.27.4 works fine, but the next release (and onwards) 4.27.5 suffer from this issue.

How often does this bug happen?
