Steps to replicate the issue (include links if applicable):

• Go to https://gerrit.wikimedia.org/
• In the search box, type red
• Hit enter to search

What happens?:
Gerrit autoselects the first entry in the search dropdown, which is is:starred, and searches for that.

What should have happened instead?:
Just search what I ask for.

Other information (browser name/version, screenshots, etc.):

• This is reproducible with any search operator. Some examples that I could see being used as search queries: "merge" (adds mergedafter:), "open" (is:open), "close" (is:closed).
• There doesn't seem to be a search button that I can click to bypass the keyboard navigation of the dropdown.
• This bug only shows when the problematic word is at the end of the search query. So, searching for color red is impossible, but red color works.
• Other workarounds are to wrap the searched word in quotes ("red"), or to put it inside another search operator (message:red). Still, the current behaviour is annoying AF if you just type in your query quickly without thinking too much.
