RichEditBox: using CTRL + i to set italic text removes text

I have the following code for bold and selected text in a RichEditBox:

private async void Page_KeyDown(object sender, KeyRoutedEventArgs e)
{
    var state = Window.Current.CoreWindow.GetKeyState(Windows.System.VirtualKey.Control);
    if ((state & CoreVirtualKeyStates.Down) == CoreVirtualKeyStates.Down)
    {
        switch (e.Key)
        {
            case Windows.System.VirtualKey.B:
                await BoldText();
                break;
            case Windows.System.VirtualKey.I:
                await ItaliciseText();
                break;
        }
    }
}

private async Task BoldText()
{
    ITextSelection selectedText = editor.Document.Selection;
    if (selectedText != null)
    {
        ITextCharacterFormat charFormatting = selectedText.CharacterFormat;
        charFormatting.Bold = FormatEffect.Toggle;
        selectedText.CharacterFormat = charFormatting;
    }
}

private async Task ItaliciseText()
{
    ITextSelection selectedText = editor.Document.Selection;
    if (selectedText != null)
    {
        ITextCharacterFormat charFormatting = selectedText.CharacterFormat;
        charFormatting.Italic = FormatEffect.Toggle;
        selectedText.CharacterFormat = charFormatting;
    }
}

BoldText()and ItaliciseText()also called from the buttons on the toolbar.

When clicked, the Boldselected text will be correctly formatted in bold.

When pressed, the CTRL+Bselected text will be correctly formatted for bold text.

When clicked, the Italicselected text is correctly formatted in italic text

When clicked, the CTRL+Iselected text is correctly formatted in italic text , but then deleted
