GeolocateControl marker shrinks when tilting and zooming map

[tricaric]

maplibre-gl-js version: 5.1.0

browser: Chrome/Firefox/Safari on Mac, and Safari/iOS

Steps to Trigger Behavior

1. open the "Locate the user" example page: https://maplibre.org/maplibre-gl-js/docs/examples/locate-user/
2. click on the "find my location" button on top-right of the map, and give permission to locate
3. wait for the map to zoom on user position, and then zoom more to have the marker clearly visible
4. alternate zooming and tilting of the map, and you will notice that the marker accuracy disk appears to shrink when you tilt the map, and then go back to its normal size when observing vertically the map

Of course here I am not talking about the expected change in apparent size due to the change of viewing angle, but to the sudden shrinking and growing of the marker after tilting and zooming, as it is clear when compared to the nearby buildings.

Expected Behavior

The marker should not shrink when tilting the map, it should stay fixed at the size given by the accuracy of the position of the user.

Actual Behavior

The marker appears to shrink when tilting the map, and then appears to grow back to its normal size when observing the map vertically.

Thanks for taking the time to report this issue.
Seems like the style of the accuracy circle should be set to viewport and not map.
PR is welcomed.
