This was seen in Browser when hotkey activations were processed twice. If we open the Inspector with a hotkey (F12) and quickly activate that hotkey again, we could try sending a JS command (inspector.loadDOMTree) before the inspector.js file was actually loaded in the WebContent. The window for this bug is larger on Serenity, where loading WebContent is a bit slower than on Linux. So even with the Browser bug fixed, it is pretty easy to hit this window still.
