"editor.suggestSelection" doesn't seem to work as a language-specific setting

[Gama11]

I was trying to contribute a default configuration for "editor.suggestSelection" in the Haxe extension as described here by @jrieken: MicrosoftDocs/intellicode#138

However, I couldn't make this work, which made me test if it even works if it's configured by the user in settings.json rather than via a configurationDefaults. I couldn't make this work as a language specific setting either, not even for TypeScript.

The following .gif shows how TextEncoder is pre-selected when completion is invoked (because I had previously selected it), despite the config in the lower panel. Only the non-language-specific setting seems to have an effect.

Please as steps. A gif complements but doesn't replace steps. Adding them will cost way less time than the time it takes me to stare at a looping gif

First, to "initialize" the completion memory, request completion after Tex in a TS file and select TextEncoder. Undo and press Ctrl+Space again, this time TextEncoder should be pre-selected due to the default value of "editor.suggestSelection" (recentlyUsed).

Add the following to your settings:

"[typescript]": {
    "editor.suggestSelection": "first"
}

Expectation: this should clear the pre-selection / select the first item when we request completion again, but instead there's no change:

Now move the setting out of the [typescript] block. Only now does the setting have an effect:

Yes - turns out this isn't implemented ;-)
