Inline completions not displayed when extending selectedSuggestionInfo range and text

[joyceerhl]

Testing #131415

1. Add the following to the body of provideInlineCompletionItems to return a dummy inline completion item

			if (context.selectedSuggestionInfo !== undefined) {
				if (context.selectedSuggestionInfo.text === 'helloworld1') {
					return [{
						text: 'helloworld1',
						range: context.selectedSuggestionInfo.range,
						trackingId: 'some-id'
					}];
				}
			}

2. Open an untitled file and add

helloworld1 = 1
hellow

3. Ctrl+Space to put up suggest widget.
4. Inline completions not displayed (?) The docstring says "provided inline completions must extend the text of the selected item and use the same range, otherwise they are not shown as preview." Here the completion I'm providing does extend the selected item in the suggest widget, and it uses the same range as what's provided in the context. I don't have context on the inline completions API beyond what's described in Inline Suggestions: Support Interaction With Suggest Widget #129495 so perhaps the docstring could be further clarified if I have misunderstood how this API is supposed to work?

I needed to also configure editor.suggest.preview--thanks for the hint @hediet :D
