[Bug] The breadcrumb bar above the editor hovering-display bug.

[UtileBread32046]

(p.s.) This is just a little display bug, not very serious.

1. When I move my cursor to the icons in the breadcrumb bar above the editor, it automatically shows the details below as expected.
2. However, when I move the cursor between two icons, the explanation may do not change to the right content.
3. It often happens when I slide directly and slowly from one to the other one.
4. The bug may occurs among several buttons and not among others.
   Apology for my poor English :)
