I have a lot of html files that show 3D objects. Edge, Chrome & Firefox show the contents without any problem. But it seems viewer pane has problems with these files.
Is there any setting somewhere that I can try?
A sample file is attached if you need to check the contents.
Most likely Internet Explorer cannot display that kind of HTML.
We'll be moving the viewer to Edge Chromium in the future, but there isn't any alternative (that I'm aware of, at least) at present. (Unless someone else has made a similar preview handler, which would also work in File Explorer's viewer pane.)
