Steps to reproduce the problem:
1. Start dragging a bookmarklet from the content of a web page.
2. Drag onto the bookmarks bar; notice that the vertical bar doesn't appear like it normally would.
3. Let go of the left mouse button.

What is the expected behavior?
When I drag a bookmarklet onto the Bookmarks Bar, I expect to see a vertical bar while I'm still holding the mouse button. When I let go, I expect to see a new bookmark entry on the bar.

What went wrong?
The UI doesn't register that I've dragged the bookmarklet onto the bar (the dragging element shows, but the vertical bar that normally shows on the bookmarks bar isn't there). It also doesn't add a bookmark when I let go of the mouse button.
