Outlook Simplified Ribbon does not show pinned item if there is no space

Question

I have a group for simplified ribbon:
<group id="someId" getLabel="GetLocalizedLabelText" insertAfterMso="GroupMailRespond" getImage="SaveAttachButtonGetImage" getVisible="ShowSimplifiedRibbon">
<box id ="SimplifiedSaveButton" visible="true" boxStyle="horizontal">
<button id="buttonId"
size="large"
getLabel="GetLocalizedLabelText"
getScreentip="GetLocalizedScreentip"
getSupertip="GetLocalizedSupertip"
getImage="getImage"
onAction="onAction"
getEnabled="getEnabled"
visible="true"/>
</box>
</group>
If I want to pin it while simplified ribbon has no space that group is not shown on ribbon and disappears from "More Commands" drop down.
But if I remove my group from Home Tab on Customize the Ribbon windows and add it again my group start respect pin action.
How can I avoid removing and adding steps to make my group respect pin action?
