Syntax highlighting uses incorrect colors after 2D array initialization

When writing the initializer list for a 2D array where one of the sizes is unknown, the syntax highlighting color for keywords changes to the "Attribute" color. For example, when writing the following in a .c or .cpp file:

int foo()
{
    return 3;
}

unsigned int test[][2] = {{1, 2}, {3, 4}, {5, 6}};

int bar()
{
    return 3;
}

The following is displayed with my current theme:

Notice how the return keyword went from light blue to a greenish-brown, which corresponds to the default value for "Attribute", which I had not modified yet in my custom theme. After changing "Attribute" to white, for example, these values now show white instead. This happens for pretty much every non-type keywords as well as preprocessor directives like #if and #else.

After some experimentation:

• I can have the initializer list be empty (i.e. {}) and the issue still arises.
• Putting an explicit size in for the first dimension (4 for this example) avoids the problem.
