Accessibility: Folding of thoughts has no impact on screenreaders

[fcnjd]

Hi,
when using thinking models, like Gemini 2.5 Pro, there is a button above the LLM's response to fold/unfold thoughts. However, this has only visual impact, for the screenreader the thoughts always stay in the DOM. It would be great if the button could:

• have an indication, like this is already the case for the sidebar, if it's expanded or collapsed
• Also show or hide thoughts for the screenreader, as this makes chats easier to read.

Thank you for all your efforts.
