Steps to reproduce the problem:
1. Log into Gcal
2. Look for normal dropdowns
3. See blank boxes instead

What is the expected behavior?
These should be "more action," "delete" etc. buttons per usual

What went wrong?
Instead, they manifest asblank boxes. Hovering over them tells their intended function via text. See screenshot. 

Did this work before? Yes Prior version
