Print chart shows empty chart with Boost enabled

[Rashaine]

When Boost is enabled the print chart functionality of the exporting modules renders an empty chart. Note: image download works as expected.

Expected behaviour

Chart with data points should be rendered.

Actual behaviour

Empty chart is rendered.

Hi @Rashaine,
Thank you for reporting. Please point me out which version of Chrome and OS you have. I was not able to replicate it on device:
MacOSX: Sierra 10.12.4
Chrome: 67.0.3396.99

Chrome: 67.0.3396.99
MacOSX: High Sierra 10.13.4

I just tried it a few more times and about half the times it renders and the other half it doesn't. Perhaps a race condition?
