insert_final_newline does not work

[BaumiCoder]

editorconfig:check and editorconfig:format do not recognize missing newline if insert_final_newline = true.

I made a little sample project here. Only insert_final_newline and trim_trailing_whitespace are set to true.

The editorconfig:check only find the trailing whitespaces. The missing newlines in the two java files are not recognized:

[INFO] --- editorconfig:0.1.3:check (default-cli) @ MavenEditorConfigTest ---
[ERROR] src/main/java/org/example/Main.java@3,20: Delete 4 characters - violates trim_trailing_whitespace = true, reported by org.ec4j.linters.TextLinter
[ERROR] src/main/java/org/example/Main.java@5,1: Delete 8 characters - violates trim_trailing_whitespace = true, reported by org.ec4j.linters.TextLinter
[INFO] Checked 7 files

editorconfig:format also only correct the whitespaces errors.

Is there some miss configuration on my site or is it a bug?
