Tooltip on Path with EllipseGeometry disappears quickly

[andyesys]

• .NET Core Version: 7.0.102
• Windows version: Windows 11, 22H2 (Build 22621.1105)
• Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes

Problem description:

When entering the ellipse with the mouse from top-left, top-right or bottom-left, the tooltip will show shortly and disappear immediately. The tooltip only stays, if the mouse is in the bottom-right quadrant of the ellipse.

Actual behavior:

Expected behavior:

The tooltip should work on the entire EllipseGeometry.

Minimal repro:

    <Canvas Margin="100">
        <Path Fill="Black" ToolTip="Hello from Tooltip">
            <Path.Data>
                <EllipseGeometry RadiusX="50" RadiusY="50" />
            </Path.Data>
        </Path>
    </Canvas>

I found a workaround by offsetting the ellipse center "into" the path by the radius amount and then using a RenderTransform on the Path to translate back. Now tooltips don't disappear on all circle quadrants.

This is a quick workaround but I think this should still be fixed properly in the framework.

    <Canvas Margin="100">
        <Path Fill="Black" ToolTip="Hello from Tooltip">
            <Path.Data>
                <EllipseGeometry RadiusX="50" RadiusY="50" Center="50,50" />
            </Path.Data>
            <Path.RenderTransform>
                <TranslateTransform X="-50" Y="-50" />
            </Path.RenderTransform>
        </Path>
    </Canvas>

Running into the same issue with a Path in a Canvas. Tooltip only stays visible when mouse is over top-left areas of the path.
