Slicer Dropdown issues- Dropdown needs to close manually and how change height of the dropdown

We have used single selection slicer as a dropdown in our report, and we are facing below issues 

1. Once the selection has made, user need to close the dropdown mannually.
we required the auto closing functionality for the slicer dropdown.

This behavious is observed with power bi desktop,services and ipad.

2. How to set height of the slicer filter, we are showing large set of values and due to predefined height,
scroll is appears.

To avaoid the scroll how can we set the height of slicer dropdown.

Requesting you to update us is there any way to fix this issues we might have missed in our developement.
