Dear colleagues from @SAP/ui5-webcomponents-topic-b,
can you please take a look at this issue.
Now only the selected toggle button is being read out.

Best regards,
Petya.

Hello @BennyHuang thanks for reporting.

We discussed the issue internally with the responsible accessibility expert and it turns out the missing readings you described are caused by the DOM structure utilising buttons, as the component is designed to slot toggle buttons.
While, on UI5 control (sap.m.SegmentedButton) side list of options ("li" elements, instead of buttons) has been used.
To fix the issue, we will need to perform bigger refactoring than expected, not just adding or replacing ARIA attributes, but changing the DOM elements, which might result in replacing the ui5-togglebutton with something else and API breaking change.

For that we will create a backlog for refactoring of the SegmentedButton, once created it will be linked here.
Then, we will close the current issue, but you will be able track the progress within the refactoring backlog (another GitHub issue at the end).

Thanks for the understanding.

BR,
ilhan

Hello @BennyHuang

as mentioned in my previous message, fixing the announcements of the SegmentedButton would require significant refactoring. For that, we created a new issue: #3191

I will close the current one, it's is referenced in the new one for traceability.
You can see the details and follow the progress here: #3191

Best,
ilhan
