Tooltip Delay/Missing

Hey guys,

Recently bought WebStorm and loving it so far but I'm having an issue. I'm unsure of it's technical name, but the tooltip that shows the 'expected' properties of something seems to sometimes be missing, or sometimes be very delayed.

For instance, if I'm referencing a model, I will type `new User()` and ideally, and functionally, the tooltip would say:

'firstName: string, lastName: string, password?'

and so on. Sometimes it does this, usually if I enter information, and delete it, and even that isn't static.

The same is true for package. jwt.sign() would normally start showing the parameters it's wanting, but more often than naught I am never able to get it successfully. Is there an option somewhere, or is this a known issue? I found a lot of similar complaints but those were about the delay - Mine is more so about it being missing.
