Add deleted files to the list in administrator/components/com_admin/script.php?

[Hackwar]

May I ask what this button did? Would we need something like this again? Somehow I had an input element of type "range" in my mind when reading this, but as a button? Anyway, good that you are removing this stuff. 😉 I don't think that you have to add any files to the deleted files list, since that most likely has to happen by script shortly before we go to RC.

@Hackwar by translating the js part <div class="collapse fade" id="collapse-${name}"><iframe class="iframe" src="${url}" height="${height}" width="100%"></iframe></div> I think this was acting like an accordion kinda thingy. So when someone was clicking on that button then the container would expand and the iframe would be rendered inside.

It is my understanding that the list is for when upgrading to handle deleted files.

[mbabker]

Someone can run https://github.com/joomla/joomla-cms/blob/4.0-dev/build/deleted_file_check.php and build a full list of files at an appropriate time. Since the entire upgrade process is messed up right now, no point in randomly adding files to that list in random PRs; enforce it after everything is caught up.
