Bug description
I've encountered the same problem as #1161, attempting to run Jest tests with amCharts. Here's a simplified worked example that reproduces the issue:
To reproduce:
git clone https://gist.github.com/davidjb/39eb1105e82cfde7ad7f200cbc00f4c6.git example cd example npm i npm t
Despite the
transformIgnorePatterns
being set, the lineimport { arc } from "d3-shape";
in.internal/core/render/Slice.js
is still triggering the issue. Temporarily removing the line moves to the problem to the next import ofd3-shape
elsewhere in amCharts.I've also tried with the latest versions of Jest and associated packages but the issue still persists. The example is using effectively the same as what's in https://www.amcharts.com/docs/v5/getting-started/integrations/jest/.
