Command syntax suggestion unclear for /effect command

Since 1.2, it appears that MCPE now reports a short list of possible enum values in place of the enum parameter in some syntax suggestions.

However, this is a problem in the case of the `/effect` command, as seen in the below screenshot:

As seen in the picture, only `true|false` is shown for the acceptable enum values for the `hideParticles` parameter. You are unable to identify what the parameter is actually for, only see the possible values.
