The Rich Text Editor handles new lines inconsistently depending on the selected text alignment. When text is center, right, or justified, the editor may automatically add a new line without you pressing Enter. When text is left-aligned, no extra line is added automatically. This difference only affects formatting in the editor — it doesn't have any further implications on how the content itself functions.
What you might notice
When text is center, right, or justified, a new line appears automatically without pressing Enter
When text is left-aligned, no automatic new line is added
Workaround
If you'd like a new line when working with left-aligned text, manually press Enter
If you don't want the automatic new line when text is center, right, or justified, manually delete it
