1643781 - Empty debugger sources after refresh with workersListener error

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P3)

Description

[:Harald Kirschner :digitarald]

What were you doing?

I refreshed on https://firefox-dev.tools/debugger-examples/examples/todomvc/ with Debugger open.

What happened?

Empty source tree, broken debugger.

Refreshing doesn't fix it. Closing and open Debugger does.

Anything else we should know?
