Visual bug with the edit pencil when sorting fields

[Loran425]

Expected Behavior

Pencil Edit icon disappears when a change in the sort order results in the cursor hovering over a field that normally doesn't show an edit icon

Current Behavior

When using the alt+s shortcut to sort fields if the pencil icon is shown on a field and a field that doesn't normally show that icon (e.g. a tag group) ends up under the cursor the edit pencil will remain on that widget until the fields widget is redrawn.

Possible Solution

Check how these icons are drawn/removed and remove the icons prior to sorting

Steps to Reproduce

1. Add a tag group
2. Add an author tag
3. Hover over the author tag
4. Press alt+s to sort the fields

Just wanted to follow-up and see if #189 resolved this issue, as I wasn't able to reproduce it before or after that PR.
