Issue Subcategory:

Content on hover/focus not dismissible

User Experience:

Users who primarily use keyboard to navigate and low vision users may be unable to dismiss overlapping content while keeping focus or pointer on the trigger, which can block nearby content or controls.

Repro Steps:

Launch Visual Studio 2026> Open any project > Open any file > Provide the below code
"// Go to Tools -> Options -> Preview Features and enable Move to File Refactoring // Select the whole line, Ctrl + . -> Move to File
int a = 0;"

Select Complete line "int a = 0;" and Press "Ctrl + ." > Move to file list item > "Add declaration to file" radio button> Observe the issue: Tooltip associated with "Add declaration to file" control cannot be dismissed.

Actual:

When the tooltip associated with the "Add declaration to file" control is displayed, pressing the Escape key dismisses the entire popup/dialog instead of dismissing only the tooltip

Expected:

The tooltip should be dismissible independently using the keyboard. When the Escape key is pressed while the tooltip is displayed, only the tooltip should be dismissed

How To Fix:

Prefer an accessible tooltip or popover component from a trusted component library that supports dismissal (e.g., Escape) without moving hover or focus, and check the library's accessibility documentation to confirm a dismiss mechanism is enabled. If a library component does not fit, provide a dismissal mechanism such as Escape and/or a close control that works without requiring users to move pointer hover or keyboard focus away from the trigger

Visual Studio 2026

Start by reproducing the issue in the WPF scenario described: open a project and file in Visual Studio 2026, invoke Move to File, and focus “Add declaration to file.” Trace the tooltip and popup behavior when Escape is pressed. Done means Escape dismisses only the tooltip while preserving the surrounding dialog, with the expected keyboard behavior verified.
