As a user makes an edit to a file, these requests are most likely no longer relevant. It also makes sure that a long-running sourcekitd request can't block the entire language server if the client does not cancel all requests. For example, consider the following sequence of requests: - `textDocument/semanticTokens/full` for document A - `textDocument/didChange` for document A - `textDocument/formatting` for document A If the editor is not cancelling the semantic tokens request on edit (like VS Code does), then the `didChange` notification is blocked on the semantic tokens request finishing. Hence, we also can't run the `textDocument/formatting` request. Cancelling the semantic tokens on the edit fixes the issue. rdar://133987424
