UI freeze when dragging bookmarks across folders

Description of the issue:
When dragging bookmarks from a folder in the bookmarks toolbar, the UI stops responding to the mouse hover, after the first folder contents are displayed.

Steps to Reproduce (add as many as necessary): 1. 2. 3.

  1. Create 3 folders on the bookmarks toolbar (Folder1, Folder2, Folder3), each populated with at least 2 bookmarks to any site.
  2. Click Folder1 and down-click a bookmark to select it. Do not release click until the final step.
  3. Drag selected bookmark up to hover over Folder2 to trigger the display of Folder2 bookmark list.
  4. Attempt to position selected bookmark in between the two bookmarks in the Folder2 list
  5. Drag selected bookmark to hover over Folder3 and attempt to position between it between the two bookmarks
  6. Drag bookmark back to Folder1, or anywhere on the bookmark bar
  7. Release down-click

Actual Result (gifs and screenshots are welcome!):
After hovering over Folder2, the contents of Folder2 UI will freeze open or closed. Folder3 will not open to show contents when hovered over. The UI does not respond to any hovering until the down-click is released. The selected bookmarks do seem to successfully move to the other folders, if the click is released in a valid area, but the UI does not make it possible to position within the folder list .

Expected result:
When completing the steps above, Folder2 contents should remain open and UI should respond to the mouse hover, indicating the projected placement in the list of displayed bookmarks. When leaving the Folder2 selection area, Folder2 should collapse. When hovering over Folder3, Folder3 should expand with its list and the UI should display the projected placement.

Reproduces how often:
Every time.
