Short description of error
When "View All" is performed in an empty Dope Sheet in Grease Pencil mode, it zooms in really far and scrolling is broken.
Upon zooming, it resets the view to frame 0.

Exact steps for others to reproduce the error


Execute "View All" (Home or Pos1 key) in the Dope Sheet.
Now try to pan the view (with middle mouse button). The Dope Sheet will sometimes go blank or jump to extremely high frame numbers.
Zooming out often resets the view to frame zero.

Antonio Vazquez (antoniov) lowered the priority of this task from Needs Triage by Developer to Confirmed, Medium.

I have tested in Windows and the dopesheet area is doing weird things when pan in MMB, also flash and the header contains NaN values.

@Alexander Gavrilov (angavrilov) Could you take a look?
