Our team is also facing problems with this. Would it be possible to increase the priority of this issue?
What would be needed is to parse all the properties of the content control to the html, so when converting from html to docx all of them are preserved. I didn’t have any placeholder whatsoever and now we have all of this added, making the content of the content control useless as it cannot be modified. We need to keep the paragraph formatting so the workaround described above is not an option for us unfortunately.
Thank you for your attention.
