Web Player no longer accepts touchscreen input from windows tablet

[RayInStl]

So far I've been really happy with the new interface, but with one exception:  I'm no longer able to use the touchscreen on my Dell Inspiron P25T convertable laptop/tablet.  The regular mouse inputs work just fine.  Any thoughts on why that may be?

Relevant info:

Windows 10 x64

Latest updates and drivers installed

Chrome Version 56.0.2924.87 (64-bit) (it's updating as we speak, so if the update fixes it, I'll post here)

I've discovered that some things still respond to the touch screen.  For example, the play/skip controls at the bottom of the page still work with the touchscreen.  But selecting playlists does not.  Neither does selecting songs if you enter a playlist, or selecting a "recently played" item.
