Translations cannot handle inline tags

[CendioOssman]

Describe the bug
Things like This is <b>very</b>important! isn't currently properly handled by our translations. It is currently split up in to This is, very and important! which makes it very difficult to translate things. It also messes up white space as it strips all surrounding white space (which is usually the right thing). But here it isn't really "surrounding".

Expected behavior
Text that includes inline tags should be translated as a single entity.

Additional context
Identifying these occurrences is probably fairly straight forward. The problem is updating them. We probably don't want to use innerHTML as that can easily lead to security issue. So the question is how to handle the tags.
