Cannot clear cache

Describe the bug

Whatever I do, I cannot clear the cache referencing a schema on yaml.schemas

Expected Behavior

schema file path should be updated

Current Behavior

Current behaviour is simple: once you setup a schema for a specific filename in yaml.schemas, it's impossible to remove it. I tried to reload the window, clear cache, clear history, restart vscode or even the computer itself, it doesn't solve the issue: the yaml file is still "ghost-referencing" a schema that doesn't exist anymore anywhere on my computer.

If a rename the file (not the schema) it's working again since it's not referencing the "ghost-referencing" schema, which I obviously removed long time ago

Steps to Reproduce

1. add a reference to a schema in yaml.schemas
2. remove it
3. clear cache, reload the window, clear history, restart vscode
4. vscode is still referencing the schema

Environment

• Windows
• Mac
• Linux
• other (please specify)

Reproduce the issue on Linux by adding and then removing a schema entry in yaml.schemas, followed by the reload and restart steps listed. The payload names no source file, test, or entry point, so trace the schema-reference and cache handling from the configuration path; done means the removed schema is no longer referenced without renaming the YAML file.
