dragging the panel with the queue button on it over the action bar container causes dom elements to be selected, which glitches the UI

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

there are a variety of ways that interacting with DOM elements overlaid on the workspace will cause selection highlights on Safari. this is pretty glitchy, and only refreshing the page clears the selection

### Steps to Reproduce

1. open safari
2. drag the queue button panel towards the action bar
3. observe a selection highlight appears over the whole canvas. it should not.

### How is this affecting you?
