@astroshim Good catch! Tested and it was working well as expected.
AFAIK there are 3 way to run a paragraph in Zeppelin note like below
1. \w keyboard shortcut `Shift + Enter` : we can't run the blank paragraph
by default.
2. \w icon button: your PR disable this one :)
3. \w RestApi [like
this](https://zeppelin.apache.org/docs/0.7.0-SNAPSHOT/rest-api/rest-notebook.html#run-a-paragraph-asynchronously)
: I was able to run the blank paragraph
I think we need to block 3rd case as well. What do you think?
