Importing types via auto-complete sometimes doesn't import the type #2631
Description
Accepting a completion that imports a type or trait sometimes accepts the completion but does not add the import for the type to the top of the file.
For example, accepting this completion:
...will sometimes not add the use std::collections::HashMap; to the top of the file. When this happens, it causes compilation to fail and I have to retry the completion or manually import the type.
Are there diagnostics available for this happening? What should I look for? My coworkers and friends using VS Code don't have this category of problem.
