Removes find next popup closing issues

[satyasaibhushan]

Fixes #1774

I have verified that this pull request:

• has no linting errors (npm run lint)
• is from a uniquely-named feature branch and has been rebased on top of the latest develop branch. (If I was asked to make more changes, I have made sure to rebase onto develop then too)
• is descriptively named and links to an issue number, i.e. Fixes #123

Also the find is behaving a bit weird (I think it is intentional)

1. The text is not being highlighted unless we type 2 or more letters and the number is not getting updated unless we press enter
2. If we type a word and removed it by deleting the letters, the highlighting is getting stuck at 2 words and the highlight is not being removed.
   Please check if these are intentional or needs some fixing

@satyasaibhushan i think the behavior you found is okay! it's actually the default behavior for the codemirror search...
