//First the script waits for page to load (line 11, 13)
//Then it adds (and thus overwrites) the property 'visibility' within the 'body' selector, but without the 'hidden' value added to the 'visibility' property (line 12)

// This script should not interfere with normal forum functionality when this bug is ultimately fixed by Bethesda/ZeniMax
