Changing attributes of iframe

I doubt Atlassian would add those flags and if they do it’ll be a loooong wait.

Try disabling the clipboard API. eg I use this package in one of my apps and the copy function still works on latest Chrome: use-clipboard-hook - npm

const { ref, copy, isCoppied } = useClipboard({
    copiedDuration: 3000,
    disableClipboardAPI: true,
  })
