+#### Fix formatting i18n attributes ([#7371](https://github.com/prettier/prettier/pull/7371) by [@thorn0](https://github.com/thorn0))
+
+Prettier 1.19 [added](https://prettier.io/blog/2019/11/09/1.19.0.html#add-formatting-for-i18n-attributes-6695-by-voithos)
+support for formatting [i18n attributes](https://angular.io/guide/i18n), but putting the closing quote mark on a new line
+broke [custom ids](https://angular.io/guide/i18n#set-a-custom-id-for-persistence-and-maintenance). This is fixed now.

+<!-- prettier-ignore -->
