Description
there is a problem with the react projects and vscode I work with. I've seen multiple similar issues across forums and here (including the one i posted before microsoft/vscode#98725) but none of them has a solid solution or at least explanation.
the problem is electron_node tsserver.js cpu usage getting easily over 100% while editing a few component long project.
- VS Code Version: 1.56.2
- OS Version: osx 11.2.3

npx creat-react--appand creating a react app, add a few component to the project. - try to edit one file.
electron_node tsserver.jscpu usage easily gets over 100%. - it happens with insider version, and also all extensions (except js/ts language features) disabled:

Research direction
Start by reproducing the reported CPU spike with the listed VS Code, macOS, and React project steps, then inspect the attached tsserver.log and compare it with behavior when editing a component. The issue does not name a repository file or test; done requires identifying the responsible tsserver activity and demonstrating that the excessive CPU usage no longer occurs.
