Filter button in User interface translation form has more whitespace than it needs

Problem/Motivation

Enable locale, head to admin/config/regional/translate, and notice that the filter button has more distance between it and other elements than seems necessary.

This may impact other forms, this is just where I happened to notice it.

Proposed resolution

• Get agreement that this should be changed
• If there is agreement to change, determine the change that should be made
• Determine if this impacts other forms
• Impement, check for side effects in other forms

Remaining tasks

User interface changes

API changes

Data model changes
