Reproduce:

• Goto cockpit EE dashboard
• place mouse over one of the line chart diagrams
• use the mouse wheel

Expected:

• the page scrolls

Observed:

• Nothing happens

Hint:
I think this is related to the "zoom" feature when a time range is selected. We might want to place the preventDefault call below the range check in this file. Or remove the "zoom" functionality altogether and not mess with the wheel event.
