Not an issue. Just an heads up. The `execCommand` feature, on which the package `copy-to-clipboard` depends on, [is now obsolete](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand). [Relevant issue](https://github.com/sudodoki/copy-to-clipboard/issues/108). The author of that package is thinking of ["deprecating the library altogether"](https://github.com/sudodoki/copy-to-clipboard/pull/100#issuecomment-726720242), which I think is the right thing to do.
