Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1322003
Description of problem:
Saved bookmark names in the searchbox dropdown aren't shortened, creating a bookmark with a long name results in a list not fitting in the screen, blocking usage of existing bookmarks and creation of a new one.

Version-Release number of selected component (if applicable):
Sat6.2 Beta Snap5.1

How reproducible:
Always

Steps to Reproduce:
1. Navigate to any page with a search bar present - for example Operating Systems
2. Create a search bookmark with long name (200+ chars)
3. Try to create another bookmark on the same page

Actual results:
As on attached screenshot - bookmarks names aren't shortened, dropdown with existing bookmarks and 'Create a bookmark' option didn't fit the screen so user can't easily create a new bookmark or use the existing ones.

Expected results:
Search drop down should fit the screen, preferably by shortening bookmarks with long names.

Additional info:
It's actually possible to create a bookmark by hitting that 'empty' last row with no text, but it's not so obvious. Also other saved bookmarks with short names will appear out of the screen too, making it impossible to manage them
