Extension being triggered for a language that isn't specified as an activation event

Type: Bug

1. Have the Python extension, and no others, enabled
2. Create a new directory, and an empty .yml file within it
3. Open that file

Expected behavior: The file opens. No extensions activate, as none are installed that have anything to do with arbitrary YAML.

Actual behavior: The Python extension attempts to activate, then crashes with this error message in the console:

Activating extension 'ms-python.python' failed: Extension 'ms-python.python' CANNOT use API proposal: telemetryLogger.
Its package.json#enabledApiProposals-property declares:  but NOT telemetryLogger.
 The missing proposal MUST be added and you must start in extension development mode or use the following command line switch: --enable-proposed-api ms-python.python

It’s not necessarily an issue, but it is incredibly annoying to open my CI config, see an error popup, think something has actually gone wrong, and then discover that Python is just choking – which is irrelevant because this project isn’t even using Python! Plus, it leaves a little spinning loader and pointless text saying the Python extension is loading, forever, because

(The details are from when I first noticed this bug; I disabled all other non-default extensions and tried with fresh YAML in empty directories before submitting this bug report.)

I’m going to transfer this over to the vscode issue tracker to see if they have any idea of what might be going on.

Just updated to the latest version and yes, the issue persists, still with the same onLanguage:yaml activation event.
