Where has Outlook's TabSearchQuery IdMso gone?

I have an add-in that added a button in a custom group to the special tabset that appears when you use Outlook's Search. A few months ago it stopped working, i.e. my group and button no longer appeared on the TabSearchQuery tab. If I do not include an IdMso for the new tab that has to be declared then it appears as a separate tab within the TabSetSearch, as you would expect, but this is noth really the behaviour I want. Giving the custom tab the IdMso of TabSearchQuery should have the effect of adding its tab group to the existing Search tab.

Has Microsoft deprecated the TabSearchQuery IdMso? Or is there some other change that stops it from working?
