STR:

  • open the browser toolbox on the debugger
  • use the iframe dropdown to select any other parent process document

The debugger will be empty, even if you move back to browser.xhtml.

Similarly to WebExtension, the browser toolbox is still using the non-EFT codepath
when moving between "iframes". This forces us to use the same trick
and force updating source-tree's thread attribute on each navigation.
A fake navigation is dispatched when navigating between iframes via the dropdown.

Also, it isn't clear if the old legacy listener codepath was forcing to refetch
the sources, but we miss something in the SOURCES resource watcher to register
again all sources of the new selected iframe.
