YAML Language Server Server-Side Placeholder (Snippets)

[exsesx]

I've encountered an issue with blink.cmp where the completion suggestions provided by yaml-language-server (yamlls) include server-side placeholders that behave like snippets. This creates a suboptimal user experience because these placeholders:

1. Are inserted automatically during completion.
2. Trigger further completions in a snippet-like way, even if snippets are not explicitly enabled (capabilities.textDocument.completion.completionItem.snippetSupport = false)

For example:

As you can see, on the second screenshot, it's not blink.cmp suggestions

• While editing a YAML file, when completing kind property (kubernetes), the server provides a placeholder-like snippet (e.g.).
• Accepting this suggestion inserts the placeholder.

Expected Behavior

I would like to intercept or completely disable this behavior, ensuring that server-side snippets or placeholder completions do not interfere with the editing experience in blink.cmp?

Question

Is there currently a way to configure blink.cmp to detect and ignore these server-side placeholders or snippet-like suggestions? Or is it something that should be handled by LSP?

Context

This issue seems specific to yaml-language-server as it includes these placeholders by default. Disabling snippet support via the capabilities configuration or modifying the server settings (e.g., disableDefaultProperties or disableAdditionalProperties) does not resolve the problem.

I believe this yaml-language-server issue could be related to this redhat-developer/yaml-language-server#161

Any guidance on how to handle this scenario within blink.cmp would be greatly appreciated.
