As per last week's meeting, this task includes the restyling of the "replace text" popup. However, do we want to consider/discuss T285415#7181689 first? If we go for that, there'd be no popup to improve. Maybe we can do just the "warn only if base text was changed" part here (which should be easy and independent from the warning layout), and create another task (or continue at T285415) for the design part?

I think adding the "warn only if changed" here is a good step, regardless of the eventual design. It's not a huge thing to add, and will I think remove a good number of annoying popups.

Change 702478 had a related patch set uploaded (by Daimona Eaytoy; author: Daimona Eaytoy):

Change 702478 merged by jenkins-bot:

[mediawiki/extensions/Wikisource@master] Show text replacement warning only if the original text has been edited

https://gerrit.wikimedia.org/r/702478

After clicking the "Extract Text" button the warning popup should only be shown if the text area is not empty or if the original text that was loaded on page load has been changed

Technically, you will only see the warning popup if the text area is non-empty and has been changed since the page loaded.

You won't see the warning popup if either:

• The text area is empty. For example, https://en.wikisource.beta.wmflabs.org/w/index.php?title=Page:Wind_in_the_Willows_(1913).djvu/16&action=edit.
• The text has not been changed since the page loaded. For example, https://en.wikisource.beta.wmflabs.org/w/index.php?title=Page:Wind_in_the_Willows_(1913).djvu/15&action=edit.
