An input element is needed to support copying to the clipboard. (Unless it isn't. That would be nice. But as far as I know it is.)

I had to put that element somewhere. I guess I didn't put it far enough away.

Do you know if making its opacity 0 is a viable alternative?

Hello!

There is Clipboard API but it requires permission from Permissions API. Unfortunately, Internet Explorer doesn't support this at all.

Change https://golang.org/cl/238477 mentions this issue: content/static/css: hide pathInput element on larger displays

Tested the change on 3840 x 2160 px display:

And on 1920 x 1080 px display:

I just changed -62rem to -50vw, so it should always "hide" correctly:

.DetailsHeader-pathInput {
  /*
   * An input element that can be selected so its contents can be
   * copied to the clipboard. We can't use a hidden element, so
   * put this visible one very far off the screen.
   */
  left: -50vw;
  position: absolute;
  top: 62rem;
}

Maybe top should be changed as well (to e.g. 50vh)?

Thank you for your time 🙇‍♀️
