 That's the browser (whichever one you're using) attempting to compensate for
your badly encoded URL. This is not behaviour you should rely on.

 In fact I don't know what browser you're using, because IE, Firefox and Opera
attempt to correct the invalid URL by converting the space to %20, not +.

 Putting that source through an HTML validator (HTML Tidy) produces:

line 1 column 1 - Warning: <a> escaping malformed URI reference

error: <...> escaping malformed URI reference
Cause:

An URI contains non-authorized characters. Or the quotes around the URI are not
closed.
Solution:

Correct the URI.
Samples:

error: <a> escaping malformed URI reference

BAD space
GOOD space
GOOD space

BAD w3c

For the first example, a space should not be contained in URL. (Even if it
works in all browsers...). This is described in detail in the RFC1738 (Look for
Unsafe)
