LSP behavior depends on selection history

[perlinm]

Summary

I have tried two LSPs (written in different languages) for inserting snippets: github:quantonganh/snippets-ls and github:estin/simple-completion-language-server. I ran into the same issue with both, making me suspect that the issue is really with how helix talks to LSPs. I apologize in advance if that turns out to not be the case.

In short, these libraries (together with an appropriate snippet config file) let me insert a snippet with something like b-e-g-<tab> (in insert mode), which for me results in the following:

In this example, the LSP also makes two cursors at locations specified by the snippet.

The issue is that the (correct) behavior above seems to (incorrectly) depend on whether the cursor/selection has changed after entering insert mode. If I do not move the cursor between entering insert mode and inserting the snippet, I get

where the cursor is now at the end of the snippet. This behavior is the same for single-cursor snippets: whether the cursor gets placed (a) where it "should" be or (b) after the snippet depends on whether the cursor has moved after entering insert mode.

Reproduction Steps

1. Install github:estin/simple-completion-language-server.
2. Add the following to your ~/.config/helix/languages.toml:

[[language]]
name = "latex"
language-servers = ["texlab", "simple-completion-language-server"]

[language-server.simple-completion-language-server]
command = "simple-completion-language-server"

3. Write the following to ~/.config/helix/snippets/latex.json:

{
  "environment": {
    "prefix": "begin",
    "body": [
      "\\begin{${1:name}}",
      "  $2",
      "\\end{${1:name}}",
      "$0"
    ]
  }
}

4. Open a latex file with helix (hx test.tex), enter insert mode, and type b-e-g-<tab>. The cursor gets placed after the snippet. This is incorrect behavior.
5. Open a latex file with helix (hx test.tex), enter insert mode, and type <right>-<left>-b-e-g-<tab>. There are two cursors at the location of ${1:name} in the snippet. This is correct behavior.
