Unexpected end of input causes the entire file to be highlighted in red

[Ostrzyciel]

I typed this into VS code:

@prefix rb: <https://w3id.org/riverbench/schema/metadata#>.
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>.
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.

<#me> a foaf:Person ;
    foaf:knows "me" .

<#you> a foaf:Person ;
    foaf:knows "you" .

<#dataset> a rb:Dataset ;
    rdfs:label "Test dataset"

There is a missing dot (.) at the end of the input, which is an error. I would expect only the last two triples to be highlighted in red. However, I see the entire file being highlighted in red:

This makes it harder to find the actual error.
