[Image] _clearFocusableChildren

Less severe bottleneck is querySelectorAll("[tabindex]"):

    _clearFocusableChildren()
    {
        var focusableElements = this.messagesElement.querySelectorAll("[tabindex]");
        for (var i = 0, count = focusableElements.length; i < count; ++i)
            focusableElements[i].removeAttribute("tabindex");
    }

It's called twice for every didAppendConsoleMessageView.
