Safari 14 seems to have unexpected `white-space: break-spaces` behavior for both `right` and `center` `text-align`.

Text align left seems to work as expected in Chrome and FF. I've attached a screenshot of a codepen.

Maybe an LFC line layout integration issue?

>Maybe an LFC line layout integration issue?
No, it's not. This content has certain styles that make us fall back to legacy line layout. Actually it's progression in LFC (see the screenshot).
