Describe the bug
When creating a new line with shift + enter it uses \ by default. But I noticed creating a new line does not render correctly when using Headers (like \H1), in this case the \ is being considered as H1. Also the Backslash \ shows up when clicking on any header.

Is there anyway to use
instead if \ when clicking shift + enter. I use MDX and i think this is a better solution than \

To Reproduce

Expected behavior
The highlighted text should be used as Header and nothing else. and the backslash should not show up in the Rich Text when highlighting text as header.
