Notebook: Missing icons

See original GitHub issue

Bug: Notebook Editor, Interactive Window, Editor cells

Steps to cause the bug to occur

Open *.ipynb file

Actual behavior

Icons are missing in some *.ipynb files. (Only large files?)

It seems like that only the icons are missing. I can click a button in the bar and see tool tips of the buttons.
