Please compare the release date of https://github.com/mozilla/pdf.js/releases/tag/v4.0.189 with the merge date of #17243 (comment), and you should be able to answer this yourself :-)

Hence you'll simply have to wait for the next release, but please remember http://mozilla.github.io/pdf.js/getting_started/#introduction (emphasis mine):

The viewer is built on the display layer and is the UI for PDF viewer in Firefox and the other browser extensions within the project. It can be a good starting point for building your own viewer. However, we do ask if you plan to embed the viewer in your own site, that it not just be an unmodified version. Please re-skin it or build upon it.
