we noticed that this happens when the series valueLabels position is set to 'insideCenter'.
We tried to reproduce this issue in jsfiddle. Sometimes, the chart can be plot but a chart with only bar will be shown first and the complete chart will be shown later while sometimes it won't (a chart with missing axis, title, etc)
The browser console will display the exact error that we encountered for both case.
Below is an example that we reproduce in jsfiddle:
