JS StaticAt and StaticInRange functions always return false

[Xuri]

From changelog:

StaticAt function - takes 4 parameters - x, y, world, [tileID] (tileID is optional - if
not specified, ANY static at that location will match)
StaticInRange function - takes 5 parameters - x, y, world, radius, tileID

After testing various methods of using these JS functions, I've come to the conclusion that they always return false no matter what.

I've tried the following ways, and testVar was always false in the end:
var testVar = StaticAt( iUsed.x, iUsed.y, iUsed.worldnumber );
var testVar = StaticAt( iUsed.x, iUsed.y, iUsed.worldnumber, 0xa68 );
var testVar = StaticAt( iUsed.x, iUsed.y, iUsed.worldnumber, 0x0a68 );
var testVar = StaticAt( iUsed.x, iUsed.y, iUsed.worldnumber, 2664 );

var testVar = StaticAt( 1500, 1629, 10 );
var testVar = StaticAt( 1500, 1629, 10, 0xa68 );
var testVar = StaticAt( 1500, 1629, 10, 0x0a68 );
var testVar = StaticAt( 1500, 1629, 10, 2664 );

var testVar = StaticInRange( 1500, 1629, 0, 10 );
var testVar = StaticInRange( 1500, 1629, 0, 10, 0xa68 );
var testVar = StaticInRange( 1500, 1629, 0, 10, 0x0a68 );
var testVar = StaticInRange( 1500, 1629, 0, 10, 2664 );
