A colleague just pointed out that a paragraph in one of our documents was completely illegible because it extended way past the screen, meaning endless amounts of scrolling to the right.
I opened the source editor in the Confluence editor and saw that that particular piece of text was generated as a <span> instead of <p>. To check if this was the problem, I changed one of the sentences to <p> instead of span, and it behaved normally again.
I managed to quick-fix the issue by selecting the affected text and re-selecting "Paragraph" in the heading options (the text was already defined as paragraph style in the editor).
Has anyone else had this problem, or know how it could have occurred? There is one Draw.io diagram after the paragraph in question, but all previous paragraphs are regular text...
