After the node rendering operation, a JavaScript pop-up window is added, and then it is closed. When adding the node rendering again, an error will occur

export const showModal = options => {
if (ipcRenderer) {
ipcRenderer.showModal(options)
} else {
const dialog = document.createElement('dialog')
dialog.style.width = ${options.width}px
dialog.style.height = ${options.height}px
dialog.className = 'rounded-5'
const iframe = document.createElement('iframe')
iframe.className = 'w-full h-full'
iframe.name = options.hash
iframe.allow = '*'
dialog.appendChild(iframe)
document.body.appendChild(dialog)
iframe.src = ${location.origin}${location.pathname}?noCache=${Date.now()}#/${options.hash}${QS.stringify(options.query, { addQueryPrefix: true })}
dialog.showModal()
const off = useEventListener(window, 'message', ({ data }) => {
if (data.hash === options.hash && data.type === 'close-modal') {
dialog.close()
document.body.removeChild(dialog)
off()
}
})
}
}
The above code generates a pop-up window and implements the closing function. In the flowchart, the operation of generating the pop-up window and then closing it is carried out. However, when the flowchart is rendered, an error occurs.

Closing the code for generating the pop-up window will prevent this problem from occurring.
