yarn yarn2

Open the included project and run yarn at root to initialize everything. This is a yarn V2 workspace project with node_modules linker, allowing a monorepo to gather its sub-packages to the top level node_modules to reference together. You can see here that node_modules has ws1 and ws2 of the inner packages.

Go to file p1.ts that attempts to use p2Function from an another package. I have put the dependency in package.json as well. Try to call the import suggestion and it is not aware of possible choice.

Uncomment the first line and see that the line works, and go to definition works. Therefore, the suggestion has a bug that can't take symlinked packages in account. Moving the p2.ts file into p2/index.ts didn't enable the suggestion either.

Open the included project, run yarn at the root, and inspect p1.ts and the package containing p2.ts. Compare the missing import suggestion with the uncommented import that works and with go-to-definition. Done means import suggestions recognize the symlinked workspace package, including the tested package layout.
