I am not interested in the issues you have with those webapps. I am asking what are the bugs of Safari's implementation of the Clipboard API, since in my experience there are none (except maybe https://bugs.webkit.org/show_bug.cgi?id=222262 if you want to consider it a bug and not a different interpretation of the specs).
I am not interested in what ticket numbers Safari has. I am interested for the fact that I have $1000+ device and the basic web stuff does not work that works in the other browsers. With the premium price I am paying for Apple, I expect them to produce working software, as much smaller companies like Firefox can do it as well.
- File tree copy-paste
Other issues include
- Scrolling Jupyter notebooks
It does not help to install as a Progressive Web App, as bugs are still present.
