canvas-tools.js isn't supposed to be included in a script file?

[ddavydov]

I'm getting same js error as described here:
http://stackoverflow.com/questions/16149147/highcharts-canvas-tools-cannot-read-property-prototype-of-undefined/24334591#24334591

The scripts are included in the following order:

#= require highstock-release/highstock
#= require highstock-release/modules/exporting
#= require highstock-release/modules/canvas-tools
#= require export-csv/export-csv
#= require jspdf/dist/jspdf.min
#= require highcharts-export-clientside/highcharts-export-clientside

As it's noted here canvas-tools.js isn't supposed to be included in a script file. But if I don't include it manually(expecting it will be lazy loaded by the highcharts) then exporting PNG or JPEG becomes unsupported.

Is there any solution to fix this?

Thanks!
