eventRect is undefined

[creage]

Description

Manual resizes of a chart sometimes causes an undefined reference in updateEventRect() call, when is executed by binding created in generateEventRectsForSingleX() in this code

 rect.on("mouseover", function () { return $$.updateEventRect(); })                

updateEventRect() expects an argument, while the binding above does not pass any.

Steps to check or reproduce

Create a chart, set auto resizing to false.

Call a resize manually (from code), and try to mouseover the chart while it is being resized.
