In the stackexchange.com - moderators page, there is a strange issue with the search text.
When I try with "ask" in the search box, it is displaying the matched entries such as Ask Different, Ask Patents, Ask Ubuntu and a partial match with a user.
But when I try with "stack", I'm expecting Stack Overflow and other Stack Overflow international sites. It is not displaying the expected result, again I'm adding space and o along with "stack", like "stack o", now it is displaying the expected result.
GIF for the same:
I didn't see any error in console and network tab. What is the cause for the issue?
