Notice that not only are leading spaces valid, but pretty much all whitespace characters and any
combination thereof seems to be valid.
Examples (999 is the actual number), verified in PHP 7.3.x:
%09999 - a leading horizontal tabulator followed by the number
%20999 - a leading space followed by the number
%09%20999 - a leading tab, followed by a space, followed by the number
