I think it can, yeah. This comes at the small cost of this code no longer matching only *strict* prefixes, though. So `$isEmbedContainer` would be true even in cases where we were comparing the same class name to itself.

```php
php > var_dump(0 === strpos('__TwigTemplate_aee336d6e9d8c7d63204036df7919fc1_2059451906', '__TwigTemplate_aee336d6e9d8c7d63204036df7919fc1_2059451906'));
bool(true)
```
In practice, I don't think that'd matter, because that case is completely uninteresting anyway. So yeah, I can make this change.
