Steps to reproduce: 1. Open any webpage in Safari 2. Select a few files in Finder and drag them onto the page. Mind the files count shown in a red circle next to the cursor in osX. Expected result: Files count shows the number of files being dragged https://i.stack.imgur.com/lNXFu.png Actual result: Files count resets to 0 once over web page opened in Safari. https://i.stack.imgur.com/f0bRL.png Screenshots and the problem title are taken from Stackoverflow question. https://stackoverflow.com/questions/27797760/dropping-multiple-files-to-safari-changes-the-file-counter-to-0
Could you please confirm which Safari (Tech Preview?) version you are seeing this with?
That happens with Version 11.0.2 (12604.4.7.1.4) and Tech Preview Release 46 (Safari 11.1, WebKit 12605.1.18.2). Also, just mentioned that it is not 100% consistent. If I drag over rapidly, it may show the correct files number. But if I cross the Safari window border slowly it always resets to 0.
Also, I was able to find a post on stackoverflow dated Jan 2015 about this issue. https://stackoverflow.com/questions/27797760/dropping-multiple-files-to-safari-changes-the-file-counter-to-0 So it seems to be there for a while now. Thanks for having a look into this!
