Hi There,

I'm using the debug panel pop-out to constantly show my debug messages - nice feature, glad it's there!

What it doesn't do is clear when the debug panel is cleared:

![debug-not-clearing](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/6/b65213870b4a041898a24870bbb5242df4764445.gif)

What the screencast shows is the debug panels being filled and then a clear-debug-message action is triggered clearing the panel but not the pop-out (the clearing of the pop-out is caused by the loop of the animated gif).

A quick investigation points to a possible solution, replacing this [line](https://github.com/node-red/node-red/blob/0c923320330c1a0a387d664f9038caca860793ee/packages/node_modules/%40node-red/nodes/core/common/21-debug.html#L437):

```auto
RED.actions.add("core:clear-debug-messages", function() { RED.debug.clearMessageList(true) });

```

with this:

```auto
RED.actions.add("core:clear-debug-messages", this.clearMessageList);

```

I can't confirm if that is correct but it did fix the issue for me.

Also since I don't know whether this is desired affect, I haven't put up a PR @ GitHub.

Tested on Node Red: 4.0.9.
