};

Current Behavior

The devtools show errors: VM361 about:srcdoc:1 failed to run code TypeError: Cannot read properties of undefined (reading 'level')

The chart works well if I remove either xAxis.axisLabel.customValues or xAxis.axisLabel.formatter.

Expected Behavior

The chart works.

Environment

- OS: macOS Sequoia
- Browser: Microsoft Edge 143.0.3650.80 (arm64)
- Framework: Vue@3

This should have been fixed in #21352.
