Chart does not Display without re-size

[BlockMechanic]

Hi

The chart only becomes visible after i manually resize the window, ie by opening developer tools (in chrome) or minimizing and maximizing my side bar. Have i done something wrong or this a bug ?

I think I have the same issue. The actual data from https://www.chartjs.org/chartjs-chart-financial/ does not display in either safari or firefox (whether or not I resize the window). It does display in Brave.
