With IndexOutOfBounds Exception. While this indeed throws an exception, it doesn't throw it on the correct place.

If the intention is to support Parsers before the InterpolationTagParser with the ParserPipeline, then in that, if condition, the slice's start position should be reverted to its original, before returning false.
