It's trying to parse within comments.

We have an include tag within comments that dirty-json is having trouble parsing. We should be ignoring anything within comments.

Also has issues with something like:

        {#
            In previous implementations, we tried using {{ svg(...) }}
            and {{ imageUrl(...) }} without success. That's because they
            are backend methods and fail through Vue (i think).

            This is worth revisiting.
        #}```

Solved this for now by converting all comments to base 64, then parsing tags, then reverting our base64 conversions.
