Summary: When accessing different content in single page application the Safari share button keeps sharing the first URL on which the user has first accessed the application. Steps to Reproduce: 1) Access, e.g., this url: https://blogs.elconfidencial.com/espana/notebook/2017-12-05/elecciones-cataluna-esperpento_1488093/ 2) Swipe left or right to another page 3) Share the link through the Safari share button Expected Results: The share button feature shares the URL of the current page the user is viewing based on the information stored in the browser history / current location Actual Results: The share button features share always the same URL of the first page the user landed on the first time, regardless of further navigation in the single page application.
The share button is a Safari feature, not WebKit (see <https://webkit.org/blog/101/back-to-basics/ for more details). Could you please report this issue to Apple via https://bugreport.apple.com ?
