Stable Release Anomaly Details

• Anomaly type: new
• Previous stable: 1.118.1
• Current stable: 1.119.0
• Users affected: 726
• Platforms: Windows, Mac, Linux

Stack summary: textModel.ts:908 (getLineFirstNonWhitespaceColumn) → codelensWidget.ts:141 (updatePosition) → codelensWidget.ts:80 (constructor) → codelensWidget.ts:249 (_createContentWidgetIfNecessary) → codelensWidget.ts:315 (updateCommands) → codelensController.ts:424. An invalid lineNumber is passed to the text model during CodeLens widget positioning, likely due to a stale CodeLens range after document changes.

Note: Other "Illegal value for lineNumber" issues exist (#315291 in diffEditor, #315704 in tokenization) but with completely different call stacks. This CodeLens-specific variant is distinct.
