When using VE on Edge, there are a few issues I have seen. However, the most major one is that when saving the page, the "save page" dialogue does not dismiss after saving the page, but the save goes through.
Steps to reproduce:
I boldly renamed this as according to reports at en.wiki this actually happens on FF and Chrome as well.
Saw this locally on Chrome once, after seeing an exception in the console for something else... Can't remember the details though. Might have involved development code.
This happened once more for me with Firefox.
I did see this error in the console (that might have prevented the save dialog from being dismissed but I don't know since I didn't investigate). "Error: Offset could not be translated to a DOM element and offset: 323 load.php:731:257"
This task is nearly two years old at this stage, and I've seen no recent reports of this problem, so it's likely this isn't a problem any more. If someone is still experiencing this problem, let me know.
