 Starting from emacs -Q:
 *  Open an html file (e.g. /tmp/foo.html)
 * Type <b
 * Start a macro with F3
 * Quickly enter > followed by F4
 * M-x edit-last-kbd-macro now shows that F4 has been inserted into the
 macro.

 I believe that this bug is, in some way, caused by 
 blink-matching-paren.
 F4 only seems to be entered into the macro when the preceding "<" is
 highlighted.

 Also, I cannot reproduce the bug when setting blink-matching-paren to
 nil.

 I originally saw this problem in 24.3, but I have just compiled 24.4
 to confirm that the bug is still present there.
