How to reproduce the issue

I apologize that I cannot provide an extremely minimal reproduction since this requires lsp which in turn requires lspconfig which does not ship with nvim by default.

But it is reasonably simple to explain:

I have nvim lsp setup with clangd. It all works fine except if I open a C++ file and issue the command saveas othername.cpp from within it.

Expected behavior

I expect that clangd will pick up definitions etc. in the new file.

Actual behavior

After the saveas command, I get the following error repeatedly printed on the command line:

clangd: -32602: trying to get AST for non-added document

From what I can see from looking at ~/.cache/nvim/lsp.log, it looks like during the saveas command, nvim did not provide a bufOpen command to clangd and directly asked for documentHighlights on the new file name. I'm attaching the relevant log file.

When I tried this with coc.nvim, it looks like it does the right thing. As a comparison, the log with coc.nvim is below:
