Goal

Determine the default behavior of the includeHidden flag in Puppeteer’s page.accessibility.snapshot() and its effect on nodes that are visually hidden, CSS‑hidden, or marked with aria-hidden="true".

Constraints

The flag’s default value is not documented, and its filtering logic varies across Chrome builds. Hidden elements can inflate snapshot size and lead to false positives in downstream accessibility tools.

Unresolved Questions

What is the current default value of includeHidden in recent Puppeteer releases?
When includeHidden is false, are nodes with aria-hidden="true" consistently excluded across Chrome channels?
Will future Puppeteer versions alter the default filtering behavior, potentially breaking existing tests?
