Description
**mapbox-gl-js version**: ^2.10.0
**browser**: Brave v1.45.127
### Steps to Trigger Behavior
https://codepen.io/gmand/pen/RwJxvbx
Open the console and try to hover near the first marker (dotted lines in the pic). You will see in the console output "hover" .
### Expected Behavior
It should trigger the listener event only when you hovering on the actual line, no matter what width is added. The line should not go passed the marker points
### Actual Behavior
The line width seems to acts as a padding. If you set the width to 40, it should only add this width to 2 directions. Seems like the rendering is correct but the way the listener is attached is wrong.

Research direction
Start with the linked CodePen reproduction and inspect the line-layer hover listener behavior around the first marker. Compare the listener's hit area with the rendered line at different widths; done means hover triggers only on the actual line and the added width does not extend beyond the marker points.
