Thank you for your understanding and continued feedback.

Expected Behavior

The APIs should have either inserted a LineBreak after every heading or shouldn't have inserted a LineBreak at all

Current Behavior

A LineBreak after first `Heading is inserted even though it isn't specified in the program.

Steps to Reproduce, or Live Example

Script Lab

1. Click Run
2. A LineBreak after the first Heading is inserted even though it isn't specified in the program.

Context

I need to use insertText. I can't use insertParagraph in my application because I have to mark some content controls in the paragraph too so I render them word by word or sentence by sentence.
