Let's make sure issue is not already fixed in latest builds first.

• I verified I can reproduce this issue on Linux against latest Integration Build of Eclipse SDK

Steps to reproduce

Same as https://bugs.eclipse.org/bugs/show_bug.cgi?id=410603

On Linux

• Open a file
• Make sure no text is selected
• Open the "old" search dialog (Ctrl + f)
• Search for something that is in the file
• Hit Enter --> The "replace" buttons remain disabled.

When using the mouse to click the "Find" button, everything works as expected.

Reproducible on

• Windows
• Linux
• Mac (??? not tested)

Considerations

I was made aware of the bug when working on another PR (see #2876 (comment)) but it turns out that my PR did not cause it so reverting the mentioned changes (see #2879) doesn't fix it (maybe that PR is part of the fix but it's not the complete fix).

Community

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.

I can't work on this right now so I'm adding the tag "help wanted". Feel free to jump in.
