Description

When after publishing a page with the structure mode open on desktop, front-end interferes with scroll after window resize (scroll is locked).

Steps to reproduce

1. Edit page
2. Press "publish" with the structure mode open on desktop / switch to "view published" mode with the structure mode open
3. Resize window below 1025px, and &structure is appended to the URL and scroll is locked
4. Also, when reloading page, it loads in a broken mode when the structure mode is dismissed

Expected behaviour

Normal page behaviour when window is resized.

Actual behaviour

Scroll is locked and reload is not an easy fix either due to the added URL parameter.
