Major ChatGPT UI symptom
Audio playback aborted simply by moving the mouse.
In a message before the latest, appearance of these message buttons requires mouse hover over the assistant message area:
New Javascript code doesn’t just hide buttons with CSS alterations: the script COMPLETELY REMOVES THE HTML when the mouse hover leaves the message area.
This means that the audio playback element is also removed, aborting the speech. One now has to sit there with the mouse in the right spot of the foreground browser to hear the audio of a past assistant message being spoken.
When: At desktop resolutions in a browser or even at the smallest media viewport widths.
Additional Concerns
Why? Hiding these buttons saves no UI room, and there is no discoverability of non-existent buttons (that then appear not as buttons). Hiding is pointless, beyond OpenAI breaking stuff.
I had a CSS script override to make message buttons permanently shown, as a reasonable person may desire (also always showing the model that had generated) - now also broken.
Solution
Do not remove these buttons from the display.
