HTML server showing duplicate snippets

[a11smiles]

Issue Type: Bug

This appears to be a continuation of #388 where snippet suggestions are showing twice in HTML files.

Here's my .code-snippets:

{
    "_LocalSettings": {
        "prefix": "_LocalSettings",
        "body": [
            "\"LocalConfig\": {",
            "    \"FromWhere\": \"App Settings\",",
            "    \"ToWhom\": \"Local Developer\"",
            "  },",
            "\"Environment\": \"Local\","
        ],
        "description": "_LocalSettings"
    },
    "_Index": {
        "prefix": "_Index",
        "body": [
            "@page",
            "@using Microsoft.Extensions.Options",
            "@using AppConfigDemo.Core",
            "@model IndexModel",
            "@{",
            "    ViewData[\"Title\"] = \"Home page\";",
            "}",
            "@inject IOptions<AppSettings> AppSettings",
            "",
            "",
            "<div class=\"text-left\">",
            "    <h2 class=\"display-5 pt-5\">App Settings (Configuration)</h2>",
            "    <p>Hello <code>@AppSettings.Value.ToWhom</code> from <code>@AppSettings.Value.FromWhere</code></p>",
            "</div>",
        ],
        "description": "_Index"
    }
}

_LocalSettings and _Index are showing twice for HTML files. For other files, there's no issue.

After further troubleshooting, if I add the scope property and assign it html, then my respective snippets only show up once.

So, it appears that the duplication happens when scope is not added to the snippet definition.

Here's my .code-snippets:

code-snippets for your project, from your extension, or your user snippets? Are you 100% sure that you have not defined them in repeated in these places?

they are for my project.

i simply created a new dotnet core web app: dotnet new webapp and added that code snippets file. then going into \Pages\Index.cshtml on the last line of the file, I press ^+[space].

On the Intellisense, you'll see both snippets showing twice each.

Using the provided snippets file and an empty test.cshtml file I cannot reproduce. @a11smiles There is workspace snippets and user snippets which are both considered for snippet suggestions. Please select "F1 > Configure User Snippets" and check if you see have user snippet files with those snippets
