Comment:

 While I believe this has been around for a while, the newly responsive
 admin design significantly changes the implications. Before, zooming in
 and out worked around the issue, since the admin menu and header regions
 could be scrolled.

 Now, the draggable regions take up almost the entire width of the screen,
 and can very easily take up the entire screen before losing scrollability
 due to kinetic scrolling. At that point, WordPress becomes completely
 unusable. When the toolbar was fixed in even the smallest viewports in
 earlier versions of MP6, it was the one thing that could get a user out of
 the frozen scrolling, with the scroll-to-top functionality and the admin
 menu access. But the toolbar is no longer fixed at narrow viewports, so
 nothing short of refreshing the page and preventing it from auto-scrolling
 back to the same spot frees the user.

 In the case of the dashboard, this doesn't cause too many tangible issues.
 But on the new/edit post screen, going past the post editor and into the
 sortable metaboxes, where scrolling immediately becomes locked, blocks
 critical functionality. Depending on the exact metaboxes configuration,
 any of the metaboxes can become inaccessible, and it also becomes
 impossible to return to the post editor. The worst, and very frequent
 scenario occurs when the publish metabox is out of view and scrolling is
 locked. There is nothing to be done but hope that WordPress correctly
 auto-saves the content and refresh the browser. '''It is impossible to
 save or publish the post'''.

 Basically, we're talking about no longer being able to reliably post with
 IE10/11 in narrow viewports (most critically on Windows Phone 7 & 8, where
 IE is the only allowed browser; IE on Windows 8 is also affected, but only
 critically in the "snapped" orientation, as scrollable regions are
 accessible otherwise). That's a pretty critical regression.
