nhn/tui.editor Repro is open this, then close it, then open this. AFAICT, opening the first file loads the root tsconfig, which contains the second file. When the second file is opened, the scriptinfo already exists and the root tsconfig is the only containing project. However, it promptly discovers the nearest tsconfig and triggers a cleanup, retaining only that project. It does not seem to actually add the nearby project to the list of containing projects, though it might later, during graph update. One quick fix might be to just skip the telemetry call that's throwing if there are no containing projects (pending graph update).
