Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

• Name of Global snippets do not appear in the suggestion list (#42530)

Upon further examination I've located the setting that causes this issue to occur.

  "emmet.includeLanguages": {
    "javascript": "javascriptreact",
  },

This setting has worked normally for at least the past 10 months, and still works fine in v1.23.1.

I also tested some JSX files. Javascript React code is showing the same symptoms both with and without that setting enabled (which shouldn't have any effect anyway).
This leads me to believe that the issue is with javascriptreact.

@sassjajc Thanks a lot for reporting and finding the connection with emmet

@jrieken In the below adopt function, the items from the end of the array keep getting deleted which is causing this issue. This actually ends up deleting almost of half the items in the array.

https://github.com/Microsoft/vscode/blob/ab78dc7eba36a6079d7123cd891b9a92f56323c9/src/vs/editor/contrib/suggest/completionModel.ts#L107-L121

When editor.snippetSuggestions is set to top, the snippets are in the front of the array and so are saved from the deletes above.

The above code is only reached when there are completion results of incomplete type and when subsequent letters of the word are typed. Since emmet contributes such results, this issue is only seen in js files when emmet is enabled

This change got introduced in ab78dc7#diff-6dba103c08842c74d9919a87c5561c11 and so the issue is only visible in the Insiders
