listbox and tree will select wrong node after mouse scroll end

remove adjust offset on mouse click #1043

• list.go , i have fixed no need to adjust offset after mouse click . because at this point, offset should be right. no need adjust

• treeview.go

• it has more complex state management which need you pay more effort to fix it

• root cause

  1. after mouse-leftdown, state changes to no movement.
  2. because state is not moving, treeview::process will change offsetY to make old selection node to be visible.
  3. As a result, tree and offsetY will change back to old place.
  4. when leftclick event, old value is used to get wrong node.
  5. User will find click to wrong node

I'd like to ask you to provide a brief piece of code that reproduces the issue you're facing, along with a meaningful description, instead of a — and I'm sorry to say that — badly documented pull request and issue that simply tells me "what I should do".

I don't even understand what the problem is.
