Bug Description
File preview shows duplicate line numbers (e.g. lines 104,105,106 appear twice) at transitions between functions in longer Go files. Reproducible: when writing a config.go with ~120 lines containing multiple functions, the preview between functions duplicates 2-3 lines. Workaround: split file into smaller Write/Edit calls.
