3.2.5 should be at Level 1. It is unclear to me why outlawing changes of
context on user initiation is at Level 1(3.2.1) whereas this allows changes
of context only on user initiation (3.2.5). They appear contradictory

Proposed Change:

Clarify the SC

Response from Working Group:

SC 3.2.1 covers different situations than those covered by SC 3.2.5. SC
3.2.1 prohibits changes of context when the "user initiation" is the act of
moving focus to a user component. Since levels of conformance build upon one
another, this particular form of user initiation is not permitted by SC
3.2.5. However, SC 3.2.5 prohibits other types of change of context, such as
notification windows opening when the user is tracking external events.

The working group believes that the ability for user agents and AT to
suppress and/or notify users about pop-up windows, along with the four
success criterion (3.2.1, 3.2.2 3.2.5 and 2.2.1) address the concerns about
changes in context without user initiation. Because there is some
functionality that cannot be supported without asynchronous changes of
context, SC 3.2.5 is a level AAA success criterion.
