Expected Result:
Incorrect position count read by screen reader for radio buttons like 'Create new', 'Autoscale' and 'Manual' under 'New collection' blade. It should read as "'Create New' radio button selected 1 of 2", 'Auto scale radio button selected 1 of 2' and "Manual radio selected 2 of 2" as 'create new' radio button is under different section(Database name) and and 'Autoscale' and 'Manual' radio buttons are under 'Database throughput Autoscale' section.

Note:
Similar issue exists with Narrator and NVDA but NVDA is reading correct position for 'Create new' but not reading count and position for 'Autoscale' and 'Manual' radio buttons.
This issue also exists for similar controls present under 'New Graph' blade of Data explorer screen for Created cosmos DB after selecting "Gremlin(graph)" option.
This issue exists throughout the application for similar control.
