What does this PR do?

The search dropdown now clears when closed.

How do I test this PR?

• open search dropdown
• type something in the input
• search if you want

try one of the following:

• close search dropdown by clicking out of it
• close search dropdown by pressing Esc
• close search dropdown by clicking a Story
• close search dropdown by clicking "Moderate comments on All Stories"
• close search dropdown by clicking top navigation tabs e.g. Moderate -> Stories

then:

• open search dropdown again
• notice search was cleared

Thanks @ALawliet! This is awesome. I'm not sure why the build is showing as failed if it passed?

Hey @ALawliet! We figured out what's happening - the branch needs to be a different name than master, otherwise it tries to trigger our build - could you update this and try again? Thanks!
