'Tokenization is skipped for lines longer than 20k characters for performance reasons ' showing when auto-suggest box shows

• VSCode Version: Latest
• OS Version: macOS High Sierra

Steps to Reproduce:

1. Import a JSON with loads of keys (the JSON is not minified and is beautified), and have a method require a parameter that uses keyof typeof on that imported JSON object. Effectively, it becomes a large amount of string values all joined by the OR operator.

2. Hold CMD over a call on that method, which brings up the more info tooltip.

'Tokenization is skipped for lines longer than 20k characters for performance reasons' shows in a warning tooltip.

I shouldn't have to see that.

SOLUTION: truncate the grey information text to an amount of characters below 20k.

Does this issue occur when all extensions are disabled?: Yes

@alexandrudima any luck on this one? Seems like a quick fix doesn't it?

Falls under microsoft/TypeScript#14662. We shouldn't return the complete list of values large union cases like this
