Research direction
The report names IntelliJ build 2026.1.3, Windows 11, JDK 25.0.3, and plugin version 3.97.6-2026.1, but no source file, test, or entry point. Start by reproducing the reported 10-second TimeoutException and tracing it from the IntelliJ plugin; done should mean the triggering operation no longer produces an uncaught onErrorDropped exception.
