LSP document symbols would appear and disappear very quickly

[AgentCosmic]

Description

I'll call this command :Telescope lsp_document_symbols. The window would open, and for a split second I can see some results showing in the window. But it would very quickly disappear and there would be nothing to select. I've noticed this on js, tsx, and py files so far.

Neovim version

NVIM v0.6.0
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3
Compiled by runneradmin@fv-az152-703

Operating system and version

I can't reproduce this (though I'm not using any of the same servers as you).

Can you upgrade Neovim to 0.6.1? That release had some changes to how LSP and diagnostics work, so could be causing this.

[AgentCosmic]

Doesn't seems to help. It could be a related to language servers cos I tried with java and it was fine. I also use cssls and html, but those depend on tsserver I think.

[calvinchoy]

I think I noticed a similar thing while editing some lua files. After language server loads I see lsp icons, then it disappears. When I go to the lines and enter insert mode the diagnostics show up again.
