The padding between the last field and the bottom edge of the form should be 40px.

There's currently no or not enough bottom padding after the last form field in a dialog. As a result, dialogs look unbalanced.

After fix:

• The padding between the last field and the bottom edge of the form is 40px
• The fix just applies for strong dialogs
• It remains 40px also when an error and/or help text appears
