Problem Description

Test Environment:
URL: https://adaptivecards.io/
OS Version: 25H2 (OS Build 26200.5761)
Browser Version: Version 145.0.3734.1 (Official build) dev (64-bit)
Tool: Color Contrast analyzer -> Launch through Accessibility Insights for Windows Tool

Repro Steps:

1. Open the above URL on the Edge Dev browser.
2. Navigate to the 'Designer' control present on the header section of the page using tab key and activate using enter key.
3. Navigate to the 'Preview mode' control using tab key and activate using enter key.
4. Launch Accessibility Insights for Windows tool and open Color contrast analyzer and select the foreground and its adjacent background color of the selected 'Preview mode' control with respect to non-selected background.
5. Verify that, luminosity ratio of selected 'Preview mode' control with respect to its non-selected adjacent background color area is less than minimum required ratio i.e., 3:1 or not.

Actual Result:
Luminosity ratio of selected 'Preview mode' control with respect to its non-selected adjacent background color area is 1.261, which is less than minimum required ratio i.e., 3:1 due to which users will not be able to identify the control is selected.

Expected Result:
Luminosity ratio of selected 'Preview mode' control with respect to its non-selected adjacent background color area should be greater than or equal to the minimum required ratio i.e., 3:1.

User Experience:
Users with visual impairments, especially those with low vision or color blindness, may struggle to distinguish the selected controls due to the insufficient contrast due to which users might not distinguish the selected and non-selected control.
