• VSCode Version: 1.7.2
• OS Version: Windows 10

Steps to Reproduce:

1. Open multiple files at a time until the tab menu is scroll-able.
2. Click on an open tab using the mouse wheel, the tab will close, but the cursor will turn into auto scroll (css: all-scroll) and when you move the mouse it will scroll the tab menu.

When closing tabs using scroll wheel click, I shouldn't need to click away to get a normal cursor.
