[Bug]: Don't use css zoom in ZoomElement

[Luk-z]

Describe the bug

The css zoom rule is a non-standard feature and should not be used.

I was rendering a full width and full height fixed div in a docsPage story.
I noticed that in firefox (it doesn't support zoom) it works as expected: the fixed div covers the story box. It does not overflow to the rest of the document page

In Chrome and Safari (they support zoom) zoom rule is used and the fixed div covers the entire docs page.

Firefox is using transform: scale() that causes the current div to act as containing block. This is what i expect from a Story box.

Chrome and Safari are using zoom and we don't have the benefit of containing block functionality
