Resolved with following spec text:

If a user agent is able to detect that accessibility technologies are in use
that cannot be applied uniformly as part of the <strong>obstruction
check</strong>, the check MUST be disabled. In some cases,
interference from accessiblity tools may be avoided by acquiring
the <strong>user image</strong> in terms of the user agent's local
rendering surface, rather than using an operating-system level
screenshot.
