Parameter hints do not get dismissed when the cursor moves

Presently, it appears that the parameter hint window does not get dismissed if it is brought up when invoking a function within the argument list of another function and you move out of the inner function's argument list. The popup changes to reflect its new position, but this is not a generally useful thing and in something like a giant argument list like a call to webpackMerge this is incredibly irritating. Couple this with the fact that the Vim extension does not dismiss the param hints when you press escape and it's pretty rough.

It would be really nice if the parameter hints were dismissed when leaving the current argument list. I can see an argument for it remaining open while navigating around the current argument list, but if the cursor leaves that list and goes to an outer list, it should be dismissed.

Thanks!

Steps to Reproduce:

1. Open a new file

2. Change to javascript mode

3. Enter the text:

   const path = require('path')
   
   Array.isArray([
     baz,
   
   ])
   

4. Place cursor on line after baz

5. Type Array.apply(. The parameter hint overlay should appear.

6. Press the up arrow.

Expected:
Parameter hint window is dismissed

Actual:
Parameter hint window remains covering code

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

Commencez par reproduire l’exemple JavaScript dans VS Code, notamment en déplaçant le curseur hors de la liste d’arguments interne ; c’est terminé lorsque la fenêtre d’indication des paramètres est fermée en quittant cette liste et que le comportement signalé est couvert par un test de régression.
