Description

When I use a string variable formatted as in the example, code after the variable is incorrectly coloured

This is what it ends up looking like for me:

I'd expect this to parse the string correctly. The output should look more like this:

Test case:

<?php

$test = 'AND [' . $foo['bar'];

// hi i am a comment
if (true) {
    print 'test';
}

Steps to Reproduce

Create a test file, test.php with the contents from the test case

Expected behavior: [What you expect to happen]

Actual behavior: [What actually happens]

Reproduces how often: [What percentage of the time does it reproduce?]
