Why does "split issue" do half assed job?

[Tarang]

On Safari you can never get to the "Split issue" as cursor focus is off just as you try to make this selection.

On Chrome this works, alas you'd imagine splitting would keep all attributes on the story the same. So for instance you have a field called "Team" then it should retain the value, alas it doesn't. 

- Also relative position in the backlog, at least should start adjacent to the story being split, alas it doesn't and you have to go and find that darn split.

In truth "split issue" ideally should land you in an edit mode for the split as one will typically make updates to the story (description, acceptance criteria etc.) and it doesn't.

Really the people who designed this likely only think in terms of 'functionality' vs. "what job is the person/team trying to do at the time?"
