\keepWithTag #'midi causing note to be one octave too low

Tiny example:

\include "english.ly"

%\version "2.12.3"

\score {

%  \keepWithTag #'notate
   \keepWithTag #'midi

   \relative c' {
      \clef bass
      bf8 a16 g   a8 d,   g ef c d
      \tag #'notate {g,1 \fermata} 
      \tag #'midi {g,1.}
   }
   
\layout { }
\midi { }

}


Behavior:

When the "\keepWithTag #'notate" line is active alone, both midi and layout
outputs are correct.

When the  "\keepWithTag #'midi"  line is active alone, the final note is one
octave too low.  But, if the "\tag #'notate {g,1 \fermata}" line is commented
out, then the final note is in the correct octave.  The above example is the
last measure of a Bach piece with the "notate" "midi" tags used to
include/exclude trill notes, and all the other instances are working correctly.

Thanks, LilyPond is a great piece of software.
