Summary0001922: Code coverage misses array assignment lines
Description

Since upgrading to Xdebug 3.0, the code coverage is no longer including the first line in some multi-line assignments.

Running the attached example I would expected 100% code coverage returned, however with Xdebug 3.0.1 it only returns 18 / 21 (missing lines 28, 34 and 43 when put through PHPUnit's --coverage-html). Rolling back to Xdebug 2.9.8 and re-running the test returns 100% code coverage as expected.

Steps To Reproduce

Run the example unit test through PHPUnit 8.5.0:
phpunit --coverage-text --coverage-filter=/tmp/Xdebug /tmp/Xdebug/ExampleTest.php

I think I see the problem, the ASSIGN_DIM opcode isn't overloaded for just coverage, just like ASSIGN_OBJ from 0001910.

Issue seems to be back?
Xdebug 3.1.3 (and Xdebug 3.1.1)

    private static function recordTokenClass()
    {
        self::$currentUse = array(     // this line is not covered
            'class' => self::$groupNamespace ?: '',
            'alias' => '',
        );
        self::$recordPart = 'class';
    }
