📝 Provide detailed reproduction steps (if any)

1. Turn on VoiceOver, press VO-V and set Typing Echo to "Characters and Words" (the default)
2. In Safari for Mac, open a page with CKEditor
3. Move focus to the editing area and type content

✔️ Expected result

VoiceOver repeats each letter as it's typed, words are spoken once they're finished.

❌ Actual result

VoiceOver says nothing while typing, not letters and not words.

❓ Possible solution

Not a solution but a crude workaround: VoiceOver will read text that's already in the editor, one can type then select all the text in the editor to hear it.

📃 Other details

• Browser: Safari 17.1
• OS: macOS 13.6.2 (Ventura)
• First affected CKEditor version: Unknown, have reproduced the problem locally in 38.1.0, in CKEditor5 Predefined builds, but not in CKEditor 4 demo.

I can also reproduce the problem using Safari Technology Preview Release 183 and with Safari 16.5 on macOS 12.6 but haven't reproduced it with any browser that isn't Safari for Mac. I cannot reproduce the problem using VoiceOver with Safari on iOS 17.1 (with virtual or Bluetooth keyboard), VoiceOver with Firefox or Chrome for Mac, or NVDA with Firefox on Windows 10.
