Disable location button when permission is denied

[ezwelty]

The location tracking button is displayed normally even when location permission has been denied:

Once clicked, the location button switches to an X icon:

Ideally, it would show as a greyed-out version of the original instead.

This is current styling:

.hutGOq:enabled {
  cursor: pointer;
}

This CSS looks nice for a disabled location:

.bGLhd:enabled {
  cursor: not-allowed;
  opacity: 0.5;
}

Google Maps has a dedicated icon and a "default" cursor, so maybe do cursor: default instead.
