Issue Summary

When inserting a macro (like the Info panel one, for instance) between two separate lines that don't have a "return" in between them, the macro is unexpectedly placed at the end of the paragraph instead of at the beginning or the end of the intended line, in the New Editor only.

This behavior deviates from the expected functionality, where the macro should be added precisely at the insertion point.

This issue does not occur in the Legacy (Tiny MCE) editor, where lines are treated differently, specially when text is copy and pasted from a different source.

Steps to Reproduce

Expected Results

The macro should be inserted at the beginning or at the end of the intended line.

Actual Results

The macro is unexpectedly placed at the end of the paragraph instead.

Workaround

Add a return between those lines first, before adding the macro.

The side effect is that this adds more space between lines.
