Adding an additional path doesn't work quite right with relative completions

[abrassel]

I'm using jsonnet-language-server with the following startup args with helix-editor

[[language]]
name = "jsonnet"
file-types = ["jsonnet", "jsonnet.TEMPLATE", "libsonnet"]
formatter = { command = "jsonnetfmt", args = ["--stdio"]}

[language-server.jsonnet-lsp]
command = "jsonnet-language-server"
environment = { "JSONNET_PATH" = "~/root" }

I have a few imports in my file that use relative paths from ~/root. However, I can't click through to definitions using the lsp. For example:

local foobar = import "relpath/jsonnet/export.libsonnet";

is a line at the top of my file. The LSP and helix, when I try to click to the symbol, emits the following diagnostics

It seems as though the LSP is saying that ~/root is the correct path, rather than ~/root/relpath/jsonnet/export.libsonnet.

Additionally, this appears to crash the lsp, as helix reports a broken pipe afterward.
