Since upgrading to Safari v15 on Mac, I encounter VoiceOver announcing "busy" much more frequently. My specific version is 15.0 (166220.127.116.11.4, 16612).
This doesn't seem to be a network issue. I have enough remaining low vision to see that a page has loaded and its content is displayed visually. Still, if I try to navigate the page with VoiceOver, I hear "busy" for every key press. If I try to refresh the page with Command+R I hear "busy". If I try to close the page with Command+W I hear "busy". If I try to turn VoiceOver off with Command+F5, I hear "busy".
If I Alt+tab away to another app, I can turn VoiceOver off, then return to Safari and try using the web page as a sighted person. This is much less feasible than it once was due to my nearly non-existent eyesight. However, it's an indication that the issue is specific to VoiceOver and not something broke within Safari per se.
Anyone else seeing this?
