Maybe it’s not the perfect answer, but I’ll give you a few tips that might help you.
First of all, stay tuned for the Microsoft Edgehtml version and not the app version itself. Press F12
in Edge you can access the option to render your page even in IE versions within the Edge itself. And in the top menu ...
goes into settings to see the HTML version of your EDGE
Version number used for Edge is based on the number of Edgehtml rather
than Edge itself. This is because Edgehtml is the engine for Edge that
is Related to Feature support change.
Translating: The version number used for Edge is based on Edgehtml’s number instead of Edge himself. This is because Edgehtml is the Edge engine that is related to changing resource support.

Even on this site you can do several validations of tag and class that EDGE accepts and in which versions will work.
Also, you can always consult the Status de Desenvolvimento do EDGE
knowing everything that he Supports, things Deprecated, in Developing https://developer.microsoft.com/en-us/microsoft-edge/platform/status/mixblendmode/
Tip: EDGE project on Github, yes it is on Github :D https://github.com/MicrosoftEdge/Status
Face what is your intention to test in other versions of Edge, only validate CSS?

Validate css and js. The Browser Stack solution was the best solution and helped me 100% in this task. I recommend.
