Yes, you can edit the HTML/JavaScript files for the Issue Edit page in a Debian system. The files are located in the /var/lib/jenkins/jenkinshome/war/static/ directory. You can edit the issue-edit.html file to modify the way the text boxes work, and the issue-edit.js file to modify the JavaScript code for the page.

It is safe to modify these files, but make sure you make a backup before you start, and use a text editor that can handle both HTML and JavaScript files. You can also use a debugger to help you track down any errors in your code.

I don't see "Jenkins."
