Describe the bug

How to reproduce the bug?

1. Create valid inline block elements such as span, b, i, em, etc. that use multiple space, tab(s), or line breaks as word separators.

What is the expected behavior?
These elements when rendered should be spaced apart by one space. HTML export whitespace should respect input whitespace.

What is the current behavior?
These elements are rendered in the editor as separate components, but appear as one word. Output html is stripped of input whitespace. Note: Component HTML is exported on new lines per element, so displayed output does render correctly, but getHtml() does not.
