Graph button not moveable

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

A 'Graph' button has appeared on my canvas.

Sorry if this isn't a bug and is a feature, but unlike menus to run a workflow etc, I can't drag it to somewhere out of the way , and there is not a feature to disable it. It seems to be stuck.

Single clicking on it it appears to offer the same functionality as right clicking on a tab to save a workflow, but with an additional feature of having an 'app' mode which I can click accidentally (but never want to use), and covering more of the canvas.

Click on graph button:

Right click on tab:

Reproduce the issue with frontend version 1.42.11 in Chrome/Chromium and inspect the Graph button's frontend implementation. Determine whether the button can be moved or disabled; done when it no longer obstructs the canvas or provides a clear way to turn it off, with the behavior verified in the frontend.
