Steps to Reproduce:

1. Use Remote SSH extension to connect to another machine.
2. Open a large project with thousands of files.
3. Do a search-and-replace that affects over a thousand files.
4. While the changed files are being saved perform a new search.
5. As soon as the last file is saved (from the replace operation started in step 3) the results of the new search get cleared.
6. You have to hit <Enter> again to run your new search again.

Does this issue occur when all extensions are disabled?: Can't test this as I'm using the Remote SSH extension

We should probably not allow doing a new search before the replace has finished
