How to supply missing end-of-system bar line?

[Trevor Bača]

Hi,

The bar line at the end of the first system below appears to be missing:

%%% BEGIN %%%

\version "2.25.3"
\layout { indent = #0 ragged-right = ##t }

{
  c'4 c'4 c'4 c'4
  \bar ".|:"
  \break
  c'4 c'4 c'4 c'4
}

%%% END %%%

Is this intentional? And, if it is, is there a way to re-supply the missing
bar line?

Thanks,

Trevor.
