[Bug]: Queue button stuck on `Shift` state after `Shift`+`RMB` click in Firefox

### Frontend Version

https://github.com/Comfy-Org/ComfyUI_frontend/commit/628facaa75ad110566bebe7c5a5209cbb34de8f8

### Expected Behavior

Queue button should revert back to normal after `Shift` key is released

### Actual Behavior

When performing a `RMB` click while holding `Shift` in Firefox (which the purpose of is to override the browser's context menu being overridden), and then releasing `Shift` before closing the context menu, it causes the queue button to be stuck in the `Shift` state (where the action is `Queue workflow to front`).

The below animation shows a normal `RMB` click, `Shift` + `RMB` (releasing `Shift` before closing the context menu), and then a single tap of the `Shift` key to fix the queue button's state.


### Steps to Reproduce

`Shift` + `RMB` click on any part of the UI.
