Issue Subcategory

Focus indicator low contrast

User Experience

Keyboard users with low vision cannot see where focus is located, making keyboard navigation essentially unusable. They cannot determine which element will receive their next action.

Repro Steps

Open VS code > Install the DocumentDB for VS Code Extension and open it > Add new Connections > Expand one of the databases > Expand a collection within that database > Double-click the Documents item > Table > Observe the issue: Keyboard focus indicator color contrast is less than 3:1 on table cells in Light 2026 and Dark 2026 themes

Actual Result

When navigating through table cells using the keyboard in Light 2026 and Dark 2026 themes, the keyboard focus indicator has a contrast ratio of approximately:

Light 2026: 1.948:1
Dark 2026: 1.857:1

These values are less than the required 3:1 contrast ratio, making the focus indicator difficult to perceive.

Expected Result

The keyboard focus indicator displayed on table cells should have a contrast ratio of at least 3:1 against adjacent colors in Light/Dark 2026 themes and should be clearly distinguishable when navigating via keyboard.

How to Fix

Adjust the focus indicator color to achieve 3:1 contrast. Consider using a thick (2px+) outline with a contrasting color, or combine outline with box-shadow for visibility on varied backgrounds.

Attachment

Reproduce the issue from the DocumentDB extension's table view by navigating to Documents and moving through table cells with the keyboard in both Light 2026 and Dark 2026 themes. Locate the table-cell focus styling and verify that the indicator reaches at least a 3:1 contrast ratio against adjacent colors in both themes.
