Zero-width space (U+200B) on dlang.org navigation panel

[H. S. Teoh]

Just out of curiosity: I noticed today that the navigation links on the
left-hand column of dlang.org have U+200B inserted after "."'s (such as
after "std."). What's the reason for this?

Incidentally, my browser is displaying it as an unknown character (a
browser bug, probably, or a screwed-up font) but I'm just curious about
why this is needed here. Shouldn't it just be straight ASCII, like
"std.algorithm" instead of "std.<U+200B>algorithm"?
