Issue Subcategory:

Hover content disappears before it can be reached

User Experience:

Screen magnification and low vision users may not be able to reach and read popup content when it disappears during pointer movement.

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 is not hoverable.

Actual:

When the tooltip associated with the "Add Declaration to File" control is displayed, users are unable to move the mouse pointer onto the tooltip content without it disappearing. As a result, users cannot hover over or interact with the tooltip content.

Expected:

The tooltip associated with the "Add declaration to file" control should be hoverable, allowing users to move the pointer over the tooltip content without it disappearing.

How to Fix

Prefer an accessible tooltip or popover component from a trusted component library that keeps revealed content hoverable, and check the library's accessibility documentation to confirm hover persistence is enabled. If a library component does not fit, ensure the popup remains visible when the pointer moves from the trigger to the popup, using CSS techniques (e.g., a bridge element or delayed hide) to keep the content stable during pointer traversal.

Done means the tooltip remains reachable while moving the pointer from the control to its content and the accessibility behavior is verified.
