Does Kindle Fire HD 8.9 inch support zooming?

My team and I have collectively spent about 5 hours trying to answer this question. When using Amazon Kindle Previewer (desktop software) you can see the zooming in the 'scale up' and 'scale down' buttons. Like iPad there appear to be three levels of zooming available in fixed layout mobi files (KF8). However when you actually open these mobi files on the Kindle Fire 8.9" HD it does not zoom.

We’ve determined that the 8.9inch Kindle Fire not support zooming. It came out late 2012 so perhaps this device is not so great for fixed layout ebooks that have lots of text, which would not be readable unless you can zoom in. In other words, fine for picture books, not good for reference books.

This introduces a bit more uncertainty in the landscape of publishing a fixed layout mobi file because you can sell it to anyone with a Kindle device, however anyone with the 8.9inch device will have problems reading a text-heavy fixed layout ebook. We already noticed this problem with the Kindle Paperwhite. i.e. it can physically/technically open a fixed layout mobi, but zooming and reading it is clunky and difficult - not a great reading experience for a large print design.

Our understanding is that the 7 inch Kindle Fire HD supports zooming, but having purchased the 8.9", we can't actually test this out yet! If you want to buy one of those, you will then be able to be sure. The KF8 files we createdo have the encoding for zooming, as you will be able to see in the Amazon Kindle Previewing application on desktop computers.

It appears that KF8 format is still cutting edge in Australia, and apparently even overseas if the 8.9inch doesn’t even support zooming.
