Luau CCL: error when setting `Humanoid.PlatformStand` on server

Setting the Humanoid.PlatformStand property to true from the server-side consistently causes this error:

FireServer can only be called from the client
  Stack Begin
  Script 'PlatformLibraries.rbx.AvatarAbilities.connectHumanoidShim', Line 217
  Stack End

This does not seem to have any effect on anything else, but errors are annoying.

Happens both in client and in studio, v0.731
