Description of problem:
=======================
If there exists at least five life-cycle environments, attempting to move a host into a new LCE/CV using the Satellite's WebUI, not all content views are visible when attempting to select the desired CV. If the user attempts to type the name of the desired content view inside of the, `Select a content view` field, nothing is populated. 

Version-Release number of selected component (if applicable):
=============================================================
Satellite 6.13.0

How reproducible:
=================
100%

Steps to Reproduce:
===================
1. Login to Satellite UI
2. Create or verify there are atleast five life-cycle environments off of Library
3. Create two content views for testing 
4. Attempt to change a host to a content view other then `Default Organization View` using the new Satellite UI and not the `Legacy`.


Actual results:
==============
User is unable to select any content view below `Default Organization View` when using the non-legacy Satellite WebUI.

Expected results:
=================
After selecting the LCE, then clicking on the `select content view`, the `Edit content view assignment` window should be dynamic and resize according to the populated CVs instead of only showing `Default Organization View`.

  AND

The `Select content view` field within the `Edit content view assignment` window should be searchable.

Workaround:
===========
If the user holds CTRL + Mouse Scroll-wheel back, the page will zoom out thus showing the other content views present but at a base 100% zoom, the only present is the first (Default Organization View).

Additional Info:
================
The following command can be used as a workaround to complete the task of switching the CV for the host when executed on the Satellite's CLI:

       # hammer host update --name <Host_fqdn> --lifecycle-environment "ENV_NAME" --content-view "CV_NAME" --organization-id <ORG_ID>
