snapToGrid not working

Hi,
I was trying to apply snapToGrid false in our Scheduler (to be able to resize events by minutes), but it is really not working. Maybe is some other config property that is blocking it.

Our config has:
{
bubbles: Object,
enableCurrentTimeIndicator: false,
intervals: Object,
isEventEditable:function isEventEditable(event),
onAfterEventRender:function onAfterEventRender(args),
onBeforeCellRender:function onBeforeCellRender(args),
onBeforeEventRender:function onBeforeEventRender(args),
onBeforeResHeaderRender:function onBeforeResHeaderRender(args),
onCellMouseDown:function onCellMouseDown(event, mouseButton, originalEvent),
onClickGridShift: function onClickGridShift(rec),
onEditShiftCompleted:function onEditShiftCompleted(args, editedShift),
onEventClick: function onEventClick(args),
onEventDoubleClick: function onEventDoubleClick(event),
onEventResize: function onEventResize(event),
onEventResized:function onEventResized(event),
onEventRightClick: function onEventRightClick(args),
onHeaderButtonClicked:function onHeaderButtonClicked(elementId),
onHeaderDragged: function onHeaderDragged(args),
onRenderHeader: function onRenderHeader(args),
onResourceSelected: function onResourceSelected(recordsSelected, mouseButton, originalEvent),
onRowDoubleClick:function onRowDoubleClick(e),
onScrollContentChange:function,
onTimeRangeClick: function onTimeRangeClick(args),
onTimeRangeDoubleClick: function onTimeRangeDoubleClick(args),
onTimeRangeSelected: function onTimeRangeSelected(args),
performance:true,
range:Object,
sortResourceBy:"name",
treeEnabled:true,
updateDebouncerWait:100,
useCache:true,
snapToGrid: false,
useEventBoxes: 'Never'
}

Could you guys figure out what could be blocking us?

Thanks
