Green fringe or halo in sky where sky meets land

Lightroom Classic 15.4.1 on Windows 11 desktop PC with HDR display enabled. In Develop mode, DNG image is adjusted using AI Sky Mask to adjust hue of sky. Develop renders correctly and the exported image renders correctly. However Library Loupe and Library Full Screen regenerate a preview with a green fringe or halo in the sky along the sky/land boundary. When switching to Library you can observe Library displaying the previous preview, then the correct Develop render, then replacing it with the incorrect regenerated preview. Reproducible on a fresh HDR merge and on separate DNG files. The bug appears to be related to the setting on the exposure slider in masking, appearing with higher exposures and disappearing with lower exposures.
