I'm running into a lot of issues like this:
For example file ej.chart.js
Problem is that loop declares variable `m` but `m` is not declared at the function `seriesRender` scope.
In turn it declares `m` in Global scope and after running line 26728
`this.renderSeries(...)` function has exact same bug - for loop without locally declared `m` and it changes `m` value,
then obviously line 26729 fails with `this.model.series[m]` m being out Array range:
it has 824 those bugs:
Please fix this as soon as possible.
