Steps to reproduce the problem:
1. Create a block element, with a text node inside it
2. Set the text node's nodeValue to start with a carriage return character (\r), charCode 13.
   ie: textNode.nodeValue = "\r\nText";
3. The \r does not collapse in the block and renders as a space character.

Here is a codepen example:

What is the expected behavior?
The \r should not render.

What went wrong?
The \r renders as a space.
