Undo #22740, removing break-word from .card

[mdo]

Fixes #24990 and fixes #25235 by undoing #22740.

This needs more thought in regards to what replace this with, but for now I want to at least have a fix for the identified problem. Consider this WIP until we have an alternative.

Hey @mdo,
I was able to look into this today and it might be a browser bug. Safari doesn't seem to follow the definition of white-space: pre when a parent element has word-wrap: break-word https://www.w3.org/TR/css-text-3/#white-space-property, specifically "Lines only break at forced line breaks; content that does not fit within the block container overflows it".

word-break: break-all with child element white-space: pre works by the way.

Edit: To clarify this is in reference to #24990
