[DiehanDrotschie]

Summary:
When adding a header (e.g., # Header) in edit mode using EasyMDE, the header formatting works correctly in the editor but does not display properly in preview mode. The header appears as plain text in the preview pane without the expected Markdown styling.

Steps to Reproduce:

1.	Open EasyMDE in any project.
2.	In the editor, type # Header for a Markdown header.
3.	Switch to preview mode using the preview button or Ctrl+P.
4.	Observe the rendering in the preview pane.

Expected Behavior:
The Markdown header should render as a large, bold title (i.e.,

).

Actual Behavior:
The header appears as plain text without proper Markdown styling.
