Uploaded HTML though post API endpoint leaves ugly

[Kornosky]

Describe the Bug

Moving over a database from Notion, and the best way to preserve the styling was by exporting with HTML. But we ran into an issue where uploading HTML gives you an ugly page-preview ONLY until you manually go in -> Edit page -> Save and then it looks good. No need to make any actual edits though.

Steps to Reproduce

1. Upload HTML via bookstack POST API
2. View page preview from book-view
3. Edit page and save
4. See preview from book-view look a lot cleaner

Expected Behaviour

To only grab div text at least, instead it's showing the html code which isn't useful for end-users. Expected behavior would be for it to be how it looks when manually saving the page via the GUI.
