    <thetext>The assertion assumed that if the UIProcess sends an Off accessibility mode during WebPage creation, accessibility must not already be enabled in the WebContent process. This doesn&apos;t hold when multiple WebPages share a process: an earlier page may have enabled accessibility process-wide via a non-Off mode, and a subsequent page receiving Off is normal.                             
                                                                                                                                                                      
The function already handles this correctly by returning early (no-op). The assertion was purely defensive and the crash it caused was worse than the silent no-op.</thetext>
