Changes

• Remove disabling

Testing

Steps

Follow the steps in cybereye issue.

Regressions

• Removing the disabling will mean the the field won't be disabled while the fetching for new entries is happening

Notes for Reviewers

There were two ways of fixing this:

1. Make the field not disabled at the risk that the user will change the input while the fetch is still happening
2. Adding more logic to the fetch table which is already huge to track that field and check is it was focused before, refocus it again.

I went for option 1. Let me know what you think
