The Post History page has a "Copy Link" button next to each edit, to allow directly linking to a specific item in the history. This opens a dialog box offering Raw or Markdown options for the link. On desktop this dialog box appears directly below the Copy Link button, where it is likely to be noticed by the user. However, on mobile the dialog box appears further down the page.

For example, in the history for Link to a specific edit in the history, tapping the Copy Link button for edit 1 results in the dialog box being a significant distance below the button, and for edit 2 the dialog box is partially off screen, preventing selecting the second option. Note that scrolling does not move the dialog box, so the second option cannot be scrolled into view in order to select it.
