Screen reader does not announce descriptive information for graph slider.
Expected behaviour
The screen reader should provide descriptive and contextual information for the graph slider. For example: “Performance graph range selected from June 1st to June 15th”.
This should include associated dates, selection summaries, and any other relevant context to help users understand what the slider controls.
Actual behaviour
Screen reader is not announcing descriptive information of slider controls. It is announcing it as 'Start percentage 90/End percentage 96'.
