@haidubogdan thank you. It makes sense that this was not caught before as
for "normal" PHP situations this problem can't manifest. The scanning stops
when the first token with a ID <> `PHPTokenId.PHP_TOKEN` is found. That will be
`PHP_OPENTAG`. That will always be present as without it we don't get into PHP
mode. This needs the embedding case to happen. The problem manifests because
`LexUtilities.findPreviousToken` will report the first token if the target set
is not found.
So the change makes sense to me. An alternative I would see is to guard the
`ts.movePrevious` inside the do-while loop like this:
```java
if(! ts.movePrevious()) {
break;
}
```
The `movePrevious` will report `false` and exit the loop for the first
element in the token sequence.
What do you think?
