New objects sporadically overlap in treeview

[charlesh88]

Summary

Creating a new object in the tree sporadically causes it to overlap an existing item:

In the screenshot, note the two tree nodes (orange arrows) getting the same top property. Refreshing the page will fix the problem.

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available?
• Does this impact a critical component?
• Is this just a visual bug?

Steps to Reproduce

Create a new item in My/Shared items, or a descendant of My/Shared items.
See that none of the following occurs.

• General borkage of tree (you cannot expand nor collpase nodes)
• General borkage of object view (uneditable, unsavable, etc.)
• The created object is overlayed on top of an existing object
• The created object is created twice
• A gap exists between tree items (you may have to scroll down)
  For true tree enthusiasts
• Add the first descendant to a parent
• Add a descendant to a parent that is alphabetically before all other siblings
• Add a descendant to a parent that is alphabetically between other siblings
• Add a descendant to a parent that is alphabetically after all other siblings
• Add a descendant to appear after a niece or nephew
  * Having many expanded sibling nodes above the node to be added seemed to helped reproduce borkage
