Nice Catch Jared.

There are two issues and we need to be sure to cover both.

Jared points out an important issue. In WCAG 1.3.1 covers his concern
since information must be accessible regardless of presentation. And TIMING
provision covers any information that cannot be read because it isn't around
long enough.

So this provision was just about distraction.

But his point is good. Perhaps the HIDING option should only be available
to "busy" or decorative moving items.

Jared's option 1 does this very nicely.

Option #2 also does it and reads better when using MUST format. However the
words "changes" needs to be changed to "it" or the list since not all are
really changes. Also the Moving in the last paragraph needs to be
expanded.

Hmmm hard to do.... maybe changes needs to stay and only blinking needs
to be added to end
