'declare function' not being syntax highlighted when editing a function above it

[rhdunn]

Given:

declare function test1($a) {
    <a>
       <b type="test">hello</b>
    </a>
};

declare function test2() {
    ()
};

()

In the type="test" attribute:

1. change the test content to {}
2. between the braces, enter " then " (so test is now {""})

After (2), declare function is now highlighted as identifiers, not keywords.

NOTE: This is in usage such as:

<b type="{if ($a) then "one" else "two"}">

Some other observations:

1. Removing the outer <a> elements and repeating the tests do not exhibit the above behaviour.
2. Removing the parameters in test1 (i.e. declare function test1()) and repeating the tests do not exhibit the above behaviour.
