Attachment: Bug 1751207 - [devtools] Allow debugging popups when a toolbox is opened for its opener tab.

This is only an issue when devtools.popups.debug is false,
when it is true, the toolbox is move and a warning message is printed
if we request to open a new toolbox.

I can't reproduce this bug. Alexandre, would you be so kind as to verify if this is still reproducible on the latest Nightly build?
