zoomend not triggered with smoothZoomAbs

[Leo POUPET]

Hi, I'm trying to use on('zoomend') but it's never triggered if I'm using smoothZoomAbs.
I'm pretty sure that :

panzoom/dist/panzoom.js

Line 899 in 9902853

 function smoothZoomAbs(clientX, clientY, toScaleValue) { 

is missing a done parameter no ?
