Cannot move the cursor outside of the <header> tag in Dreamweaver Design View

I'm encountering an issue in Dreamweaver's Design View.

The document structure is very simple: I have a single <header> element with an <h1> tag inside it.

When I try to move the cursor outside of the <header> to write additional content, it stays stuck inside the <header> tag!!

Clicking or double-clicking below the <header> in Design View does not allow me to move the cursor outside of it.

Pressing Enter also adds new paragraphs (<p> tags) inside the <header> instead of moving the focus outside.

Normally, in Design View, you should be able to double-click below any element (such as a <header>) to move the focus and start editing outside of that element. However, this does not work in this case.

The only way to resolve this is to switch to Code View, place the cursor manually outside the <header> tag, and then switch back to Design View to continue editing.

This issue seems to be a limitation or bug in the Design View functionality. Could you please provide guidance on how to address this or confirm if this is a known issue?

Environment Details:

Dreamweaver Version: 21.4
Operating System: windows 11

Thank you for your assistance!
