Version:
   Qt Creator 4.10.0-beta2 (4.9.83)
   Based on Qt 5.13.0 (Clang 10.0 (Apple), 64 bit)

macOS 10.14.5 (18F203)

The first time I open a document Qt Creator does not send a
textDocument/documentSymbol request to my language server, so no
Ouline appears. If I close and once again open the document (in the
same Qt Creator instance) the textDocument/documentSymbol is sent, and
the Outline is filled in by Qt Creator with the information obtained
from my language server.
