[Bug]: Storybook is messing with query params

Describe the bug

I remember we already had issues using standard URL Encoding while using v6 so we settled to use base64 instead (using atob/btoa). Now, after upgrading to v7 RC8, I've noticed that changing a globalTypes will mess up my value.

To Reproduce

Open site with query string included (this is a valid base64 string):

&foo=aW1wb3J0IHsgdXNlU3RhdGUgfSBmcm9tICdyZWFjdCc7CmltcG9ydCB7IEFjY29yZGlvbiB9IGZyb20gJ0BnZG0tdWkvcmVhY3QtY29tcG9uZW50cyc7Cgpjb25zdCBDb21wb25lbnQgPSAoeyAuLi5wcm9wcyB9KSA9PiB7CiAgY29uc3QgW2V4cGFuZGVkLCBzZXRFeHBhbmRlZF0gPSB1c2VTdGF0ZSgpOwogIHJldHVybiAoCiAgICA8QWNjb3JkaW9uCiAgICAgIGV4cGFuZGVkPXtleHBhbmRlZH0KICAgICAgb25DaGFuZ2U9eyhldnQpID0%2BIHsKICAgICAgICByZXR1cm4gc2V0RXhwYW5kZWQoZXZ0LnRhcmdldC5jaGVja2VkMik7CiAgICAgIH19CiAgICAgIHsuLi5wcm9wc30KICAgID4KICAgICAgPEFjY29yZGlvbi5IZWFkZXI%2BVGl0bGU8L0FjY29yZGlvbi5IZWFkZXI%2BCiAgICAgIDxkaXY%2BVGVzdCBJbSB0aGUgY29udGVudCBvZiB0aGUgYWNjb3JkaW9uPC9kaXY%2BCiAgICA8L0FjY29yZGlvbj4KICApOwp9OwoKIGV4cG9ydCBkZWZhdWx0IENvbXBvbmVudDs%3D

Change something custom in globalTypes.

Query string becomes (a completely invalid base64 string):

Additional context

Not sure if this existed in v6 before or its a new issue. It's also interesting that it's not always reproducible, changing globals completely clears out all custom query strings sometimes for some reason.
