Links to Office documents do not work in Office Web Add-ins

Hi,

we are creating an Office Web Add-in for a customer. Aim is to be able to publish SharePoint content, mainly Office documents, to end user in a simple way through add-in in Word and PowerPoint. Now we found out that Add-in is blocking links to Office documents but opens nicely e.g. PDF and txt documents. Links to web pages open in a new window.

You can test this by e.g. pointing a source location in manifest file to SharePoint document library and you will notice that Office documents do not open nor do I receive any error.

Is this something which can be configured or a feature to block links to Office documents? Is there something we can do through scripting etc?

Thank you for your ideas and help.

Kind regards,
