I found a site that seems like it would be fun to try to build games in ( outside of Roblox or Minecraft) called Dot Big Bang https://dotbigbang.com/social they have a GUI builder but also coding and it's 3D out of the box.
The difference was that in the past, IE didn't follow standards and tried to take away the web from standards based browsers. And now, it's Safari that is lagging on the standards - not so much that Chrome is adding non-standard features, it's that Safari is refusing to adopt them in a timely basis.
