Steps: 1. Open Inspector[1] 2. Right click, select "Reload Web Inspector" 3. Right click, select "Inspect Element" to Open Inspector[2] Expected: Inspector[2] gets opened Actual: Nothing happens. No errors in the console. To be able to open Inspector[2] Safari needs to be restarted.
Turns out "Reload Web Inspector" has nothing to do with this bug. Second level inspector can't be reopened period. Steps: 1. Open Inspector[1] 2. Right click, select "Inspect Element" 3. Close Inspector[2] 4. Right click on Inspector[1] again, select "Inspect Element" Expected: Inspector[2] opens Actual: Nothing happens. No errors in the console.
