[XeTeX] bidi and fontspec

I believe I've run into a bug in the interaction of fontspec and bidi in 
the 2016 TeXLive distribution.  However, it appears to be so simple to 
trigger that I'm wondering whether it's something I'm doing.

The WME is:

The number 12. The number 34.56. Some more text.

The result of running xelatex on the above is the text:
The number .12 The number .56.34 Some more text.

You'll notice that the two numbers appear in reverse order across the 
periods--that is, if you have
in the input file, you get
in the PDF.  But the digits inside <number> are in the correct order.  
Other punctuation that I've tried (including the comma) do not seem to 
trigger this bug, only the period.  (Hexadecimal digits A-F block the 
reversal, too :-).)

Loading fontspec seems to be necessary for this bug to happen.  And I'm 
not actually invoking either bidi or fontspec.

Can someone reproduce this?
