Email Signature Images Width and Height Lost

We can now confirm that this is happening within our own personal Outlook for Web account. 

The problem is actually more significant than only images losing their width and height, much of the styling/formatting of the signature gets erased, including font styles and more.

This is a significant step backward in support for email signatures for Outlook products. We had great hopes that "New Outlook" might solve some of the issues that existed in past versions of Outlook with HTML signature support, and 2 weeks ago it seemed like that was true. 

This is significantly damaging our business along with every other email signature software business out there. Would someone at Microsoft please comment whether this is a temporary issue that will be resolved, or a permanent change?
