@EbuD99 Thank you for reporting the problem to us. For a sake of correction it has been logged as WORDSNET-24217. We will keep you informed and let you know once it is resolved.
The problem occurs because because header text wrapping around floaters is not implemented in Aspose.Words layout. We plan to start work on this issue in October, but currently it is hard to predict how long the work might take.
@EbuD99 The issue is postponed until the main WORDSNET-9957 issue is resolved. The main issue is currently under development, but, unfortunately, no estimates are available at the moment. We will be sure to let you know once the problem is resolved.
