- we don't need to use _.escape from lodash as we already have escapeExpression from handlebars
- it's more correct to use the escape utility from our theme engine when escaping strings _for_ our theme engine!
- Note there is a minor difference between the two:
- Lodash: &, <, >, " and '
- refs: https://lodash.com/docs/4.17.15#escape
- Handlebars: &, <, >, ", ', ` and =
- refs: https://handlebarsjs.com/api-reference/utilities.html#helper-utilities
- This could cause slightly weird behaviour in themes around ` and = characters, but as it's just convering to html entities it should be fine
