Idempotency bug w/ unclosed multiline string

[Caleb Jasik]

When prettier-plugin-go-template@0.1.2-beta.5 is given:

{{ defi "Norwegian krone#
    "dialing_code" "+47" 
    "dialing_code" "+47" 
}}

it first formats it as

{{ defi "Norwegian krone#
  "dialing_code" "+47"
  "dialing_code" "+47"
}}

and on a second format as

{{ defi "Norwegian krone#
  "dialing_code" "+47"
  "dialing_code" "+47"
  }}

Is # a valid beginning to some go template clause? It reads to me like this should be an error, but I'm unsure...
