AFAIS that's not a mistake, that's implemented

See elisp info node 34.3.1.2 Character Classes


`[:space:]'
     This matches any character that has whitespace syntax (*note

....


Here is a table of syntax classes, the characters that stand for them,
their meanings, and examples of their use.

 -- Syntax class: whitespace character
     "Whitespace characters" (designated by ` ' or `-') separate
     symbols and words from each other.  Typically, whitespace
     characters have no other syntactic significance, and multiple
     whitespace characters are syntactically equivalent to a single
     one.  

======> Space, tab, newline and formfeed <============

are classified as
     whitespace in almost all major modes.

[:blank:] should DTRT.
