Close file icon is not displayed until mouse is moved

[redmunds]

1. open 2 files in working set
2. move mouse over first filename in list
3. move mouse over (x) icon
4. click on (x) icon without moving mouse

Results:
first file is closed, and mouse is over filename that was second (now first), but (x) icon is not displayed. I have to move mouse to get (x) icon.

Expected:
(x) icon is immediately displayed

QRB reviewed. Worth fixing but we want to wait until design is finalized.
