Breaking changes in windows update 1903 for outlook office JS based add-in

We noticed few breaking changes after installing latest windows update with regards to office JS based add-ins.

  1. The add-in host browser is changed from IE to edge.

  2. There are breaking changes with links, previously inside add-in if you have an anchor tag with target="_blank" it used to open in a new browser window. Now its opening inside a new window with in Office browser(same as dialogApi dialog) if domain on target page is same domain as add-in domain.

  3. From the dialog we are not able to open new page, all links to other domain fails.

I could not see any information about introducing the new browser in the release notes for Update 1903.

Is there a way to make the links open in a new browser window(as before upgrading to 1903) regardless of domain?

The new functionality of anchor tags is by design.

I am unable to reproduce the errors opening links to other domains in the dialog. What exactly is the error you're seeing?
