This issue is raised when I scanned a webpage https://www.irctc.co.in/nget/train-search using axe extension. I didn't do anything special. We informed the same issue with the axe extension team thinking it may related to how extension handles axe-core.

I'm able to load axe-core v4.9.1 directly on the page and perform a scan without issues.
