// Note that: | |
// - You may not need this. `navigator.clipboard.writeText()` works directly in all modern browsers as of 2020. | |
// - In Edge, this may call `resolve()` even if copying failed. | |
// - In Safari, this may fail if there is nothing selected on the page. | |
// See https://github.com/lgarron/clipboard-polyfill for a more robust solution. | |
