Describe the bug
The Variable Manager panel stays open when you switch to a different page. It floats over the new page even though you never asked for it there.

To Reproduce

1. Open any page in the builder
2. Click the Variables icon in the left sidebar to open the Variable Manager
3. Switch to a different page
4. Variable Manager is still visible, floating over the new page

Expected behavior
The Variable Manager should close when navigating away from the page. If needed on the new page, the user can re-open it manually — same as how most floating panels behave.

Screenshots/Video

Additional context
Not a blocker, but it feels unintentional and a bit disorienting — especially since the new page has nothing to do with what you were editing before.
