It is an upstream bug in the treesitter grammar itself, unfortunately: https://github.com/camdencheek/tree-sitter-dockerfile/issues/4

There is a workaround, but I think its brittle and ugly to have to use the backslashes all over

There is no heredoc in this screenshot, so the problem doesn't exist. If you mean to use backslashes and && instead of a heredoc -- yeah that's always possible, I'm very used to it.
