Fix placeholder position check (#1216)
* Fix placeholder position check

Because of the missed negation `placeholderPosition` could actually point to a different comment. As a result loaded comments would be displayed at a wrong position which could result in duplicated comments.

* Extract placeholder search code

Simple refactoring. The only notable change is that now technically `placeholderPosition` can be -1. In practice that should never happen, but I added checks anyways
