Question Inverted shadows on shadow cascade border in WebGL (2022.2.14f1)

Hi everyone,
I am experiencing a weird problem with shadows when building for WebGL. For some reason, there is a circle around the main camera that inverts the shadows on the terrain (see attachment). I can't figure out what causes this problem since it doesn't show up while playing the game in Unity. I did figure out that the line occurs at the distance of the shadow cascades that are set in the UniversalRenderPipelineAsset. does anyone have an idea what can cause this? I already tried turning the cascade count to 1 but that removes the shadows completely when building.
