Using \breakAlignInsert to put a clef change after the key signature

[Knute Snortum]

I have a situation where there is a clef change after a volta repeat and I
want the cautionary clef printed outside the repeat bar line and after the
cautionary key signature.  I thought I'd use the new \brealAlighIinsert
function for this, but although the output is correct, there is awarning in
the log output:

programming error: No spacing entry from KeySignature to `clef'

Below is my MWE and I've attached a picture of the output.  What am I doing
wrong with the \breakAlignInsert function?

%%% Start
\version "2.26.0"

\relative {
  \key f \major
  \repeat volta 2 { \*8 f'1 \break }
  \breakAlignInsert #end-of-line-visible clef after key-signature
  \key f \minor
  \clef bass
  \*8 f,1 |
}
%%% End
