This ensures that the text and the close icon don't overlap, regardless
of the length of the title. The title div grows to use all available
space, while ensuring the text breaks if necessary to prevent it from

Avoid various uses of html_safe

We can avoid using `html_safe` in various circumstances, through alternative approaches like i18n keys ending in `_html` or using `safe_join` to avoid converting via unsafe string types.

The `_html` keys approach only work for ActionView helper version of `t`, not the base `I18n.t` method.
