chart.update('none') while animations are in progress is lost

[kurkle]

Expected behavior

When update('none') is called, already running animations are updated with new values - or the animations are aborted (bad, but at least the result is correct)

Current behavior

While fixing issues in zoom plugin, noticed that if there is an animation (zoom) ongoing and during that zoom user pans the chart =update('none'), points (in this case it was a scatter chart) end up in the wrong places. Panning again fixes the chart.

What happes is:

• animations are running, having for example some target coordinates for the points
• update none updates the points directly with correct values
• next frame, the animations override those directly updated values with the next step in animation - the update is lost
