No back Code Action ,when cursor in diagostic range.

[erasin]

When I move cursor to diagostic range, I want get code action, but callback nothing.

If I select diagostic range, lsp will back.

I think if cursor in diagostic range and get back action tip is better.

file: demo1.dot

graph demo {
	"Bowser" ->  {"Chrome" "firefox" "Safari" "..."}
}

cursor in range : no action

 -> {"jsonrpc":"2.0","method":"textDocument/codeAction","params":{"context":{"diagnostics":[{"code":"DOT4000","message":"Invalid edge operation, use \"--\" in undirected graph","range":{"end":{"character":12,"line":1},"start":{"character":10,"line":1}},"severity":1}]},"range":{"end":{"character":11,"line":1},"start":{"character":10,"line":1}},"textDocument":{"uri":"file:///Users/erasin/Development/uml-demo/demo1.dot"}},"id":41}

cursor select diagnostics: have action back
