I've encountered an issue where arrow icons at the marker ends of a graph layout are missing when the layout is set dynamically using a dynamic action. This issue seems to occur consistently under the following conditions:
Here is the code used:
const { self } = apex.region('graph'); self.settings = { ...self.settings, layout: 'force' };
Result:

If we look at the browser console, we can see that the marker end is missing
