Grouped boxplot boxpoints overlap boxes

I’m trying to create a grouped boxplot with boxpoints set to all. This works fine as can be seen here: https://codepen.io/wacmemphis/pen/ZERwryG

However, the points overlap the boxes slightly. Even when I increase the height of the chart, the overlap doesn’t really disappear even though there are huge gaps between the different y-axis categories.

Anyone got an idea why this is happening and how to fix it?
