sarif-vscode-extension: Entering any text in any file is causing numerous launches of rg.exe processes causing global system slowdown

Type: Performance Issue

After opening a large project in VSCode, I found my system performance was slowing to a crawl whenever typing in any text. Doing an ETW trace found hundreds of rg.exe processes being launched in a very short period of time.

These all had a command line like this: "c:\Users\XXXX\AppData\Local\Programs\Microsoft VS Code\resources\app\node_modules.asar.unpacked\@vscode\ripgrep\bin\rg.exe" --files --hidden --case-sensitive -g **/untitled:Untitled-1 -g !**/.git -g !**/.svn -g !**/.hg -g !**/CVS -g !**/.DS_Store -g !**/Thumbs.db -g !**/QLocal -g !**/obj -g !**/objd -g !/__cacheOutput --no-ignore --follow --no-config --no-ignore-global

This caused system-wide slowdowns and made VSCode largely unusable. Using VSCode’s Extension Bisect feature narrowed down the culprit to being this extension.

After disabling this extension, the problems went away immediately.

These slowdowns were observed in any type of document, even untitled ones.
