Storybook 8.6 runs a11y addon on autodocs page

[joonass-visma]

Summary

When upgrading our Storybook to v8.6 I noticed some lag/slowness when navigating to autodocs pages with lots of stories. Chrome dev tools performance check lead me to axe-core package which is used by a11y addon. If I remove the addon from the build, the lag is gone. So clearly it's running the a11y checks on the auto-docs pages. Just wondering is this feature or a bug, because I was under the impression that a11y checks are only run when you're viewing specific stories?

Additional information

We use webpack and react v19.
