Revert "It appears that this hack is no longer necessary *crosses fingers*"

This reverts commit c05056ce86b06cff154d21a2fdd3bb0340fb099a.

For future reference, exact details about why this hack IS necessary:

> Very recently I'm having this trouble where as I'm typing in letters
into the Category field, when the dropbox appears for options, it
blanks out my cat field after a second, so I need to add or subtract a
typed letter to be able to see what I'm typing, which is kinda hinky.
