Needed here, as the at the time that I was getting the position from the offset, the model could have changed and the position could be different.

vscode/src/vs/editor/common/services/treeSitter/treeSitterParserService.ts

Lines 280 to 290 in b4a24bc

	private _applyEdits(model: ITextModel, changes: IModelContentChange[]) {
	for (const change of changes) {
	this.tree?.edit({
	startIndex: change.rangeOffset,
	oldEndIndex: change.rangeOffset + change.rangeLength,
	newEndIndex: change.rangeOffset + change.text.length,
	startPosition: { row: change.range.startLineNumber - 1, column: change.range.startColumn - 1 },
	oldEndPosition: { row: change.range.endLineNumber - 1, column: change.range.endColumn - 1 },
	newEndPosition: { row: change.rangeEndPosition.lineNumber - 1, column: change.rangeEndPosition.column - 1 }
	});
	this._newEdits = true;
