I have two tabs with identical first letters in names.

I appoint various KeyTip on them, but second tab display header not KeyTip о_О

Code example:

<Fluent:RibbonTabItem Header="Panels" Fluent:KeyTip.Keys="P"/>
<Fluent:RibbonTabItem Header="Perforation" Fluent:KeyTip.Keys="R"/>

Image Example:

How make so that the second tab to display KeyTip "R"?
