Explain the meaning behind this SC

Response from Working Group:

A number had to be chosen for testability per the WCAG requirements
document. The following rationale for 3 seconds is provided in "How to Meet
Success Criterion 2.2.2":

"Three seconds was chosen because it is long enough to get a user's
attention, but not so long that a user can not wait it out if necessary in
order to use the page and the blinking blocks their ability to focus on the
page."
