vscode: [perf] UI stalls and freezes when searching single whitespace

• vscode repo
• open search vielwet
• expand replace part of the widget
• search for a single space
• in the file-include box type out **/electron-browser/**/*.test.ts
• 🐌 notice how everything becomes sluggish

The performance trace shows some really long tasks that are preceded by some also long work
