Enable delayOpenNotifications=true with LSP client vNext to prevent redundant didOpen/didClose notifications to server #5176
Description
See microsoft/vscode-languageserver-node#848 (comment)
textSynchronization: {
delayOpenNotifications: true,
},This will prevent redundant didOpen/didClose events being sent from VS Code to the LSP server when holding Ctrl and hovering over something (which triggers some work for the open file, such as sending outline notifications etc.).
