isElementWithinMarker returns false also in serverside

[javinotfound]

Describe the bug
In some cases, isElementWithinMarker returns false. However, it should return true. This occurs with markers created serverside, and isElementWithinMarker created also serverside (I say that because it could be related with #516

To reproduce

1. Change your MTA nickname to "Test"
2. Execute next code

function myTestBug()
local player = getPlayerFromName("Test")
local x,y,z = getElementPosition(player)
local marker = createMarker( x,y,z, "cylinder", 20.0, 255, 0, 0, 255)
if isElementWithinMarker(player, marker) then
outputChatBox("Works fine!", player, 0, 255, 0)
else
outputChatBox("Fail detected!", player, 255, 0, 0)
end
end

Expected behaviour
If isElementWithinMarker is working properly, you should see Works fine!, but in chatbox it showed Fail detected!
