Steps to reproduce the problem:
1. Restrict the size of text content that includes either single spaces or line-breaks to smaller than a word when using white-space: pre-wrap (word-wrap: normal)

What is the expected behavior?
Existing line-breaks should be used or replaced instead of new ones added at the same position. Wrapping words separated only by spaces should not introduce empty lines containing only white-space.

What went wrong?
Wrapping at the end of the word introduces a line-break if there already was one, producing a new completely empty line.

Two consecutive words that don't fit separated by a single space results in three lines of text, including one line just for the space.
