Firefox zoom implementation breaks position: fixed elements in Docs
See original GitHub issueDescribe the bug
In Firefox, the zoom feature uses transform styles (see https://github.com/storybookjs/storybook/pull/12845) - unfortunately this breaks positioning on elements that require position: fixed when in the “Docs” view.
Normally a position: fixed element’s position would correspond to the viewport but in Firefox it corresponds to the element with the transform style.
The issue is present regardless of actually using the zoom feature. I have tried to disable the zoom feature (related feature request: https://github.com/storybookjs/storybook/issues/16771) in the hopes that it might also remove the styling used for zoom, however, the styling remains.
To Reproduce I created a simplified reproduction of the issue here: https://github.com/idesigncode/bug-storybook-firefox-position-fixed
To view the issue, open the story in Docs view in both Firefox and another browser.

Additional context My actual use case is documenting a tooltip component that uses fixed positioning to stay within the window.
Here’s some screenshots of the simplified example:

Firefox ❌
Firefox (with the transform style disabled) ✅

I do not expect there is an ideal fix here as the inconsistency lies in the browsers’ implementation of the
transformstyle…But if I may propose an alternative: only apply the
transformstyle if the zoom feature is not disabled.I believe the zoom feature is the only reason to use the
transformstyle in the first place, so applying it while this feature is disabled seems unnecessary.Thanks @idesigncode just got around to cloning everything and looking at issue repos so Ill check back if I see anything!
