Emacs LilyPond mode: Indentation after a beam

This is an issue in the Emacs LilyPond mode.

In the following example the indentation of lines following the end
of a manually set beam is wrong.

\version "2.24"
\relative c'{
  <c e>8[ <d f>]
      <e g>  %% run (Lilypond-scan-containing-sexp) in this line
    }

As a workaround put something in between the characters ">" and "]", like:
<d f> ]
<d f>8]


Best regards
