Saved search dialog not appearing when using WEBUI on Mobile Phone

When using WEBUI on Chrome/Safari browser on mobile phone, clicking the Save As button doesn't display the Save Search dialog.

Steps to Reproduce

• Open Chrome or Safari browser on mobile phone
• Navigate to WEBUI (can be nightly.nuxeo.com)
• Perform a Search
• Click 'Save As' button
  Expected Results: Save Search dialog appears
  Actual Results: Nothing seems to happen

Note: If the phone is rotated horizontally so that the view flips, the user is able to see the Save Search dialog. It just doesn't appear when phone is vertical.
