Since 1.94 (and it's hotfix) using profileNamespace getVariable ["var", 0.5] in CfgUiGrids (custom layout item) forcefully sets the grid position to 0.

This is happening because 1.94 switched to BIS_fnc_parseNumberSafe. profileNamespace and getVariable are not in the "MATH_OPS"` array which checks tokens in the string, so it thinks the string is "unsafe" and returns 0.
