Hide filename edit field when there is no image

Hide |filenameEdit_| line edit box when there is no image to be displayed.
This fixes an undesired grey line appearing as the bottom of this edit box.
Changing the "disabled" state doesn't change the style of this box,
"disabled" state is only used for read-only behaviour not style.

Has the new attempt from #12 verified as working as anticipated and not flakey?

Yes, this is also showing up in Chrome Canary.  is it possible its already been merged?

Canary doesn't need to be merged.. It's picking up from ToT.  You only need to merge post-branch.  

To be clear, are you saying the problem is resolved when you check on it in canary?

Correct.  I may have requested a merge in error.

Removing merge request per #19
