When I run the project in the preview version (the "Run layout" button), the boxes doesnt move at all, and everything is very stable. As it should be.

I have the same issue regardless if I run the exported html file locally or from a server.
I made a new test project to test this issue, and I got the exact same results. Here is a project file example:
