ICS filename hardcoded to 'addtocal.ics', should use Title.

Adding Fork and merge request.
Updated Remaining tasks and status.

@Maintainers, is there a timeline for getting some of these 3.0.0-beta1 issues resolved? I am at the point where multiple composer patches are conflicting. If no one is able to commit time to this project feel free to put out an issue looking for co-maintainers so we can get some of these issues past the finish line, cheers!

@ChrisDarke, I've tested this on 3.0.0-beta1, and I saw the file name change from 'addtocal.ics' to 'Test basic.ics' on the creation of the file. If what I described hasn't been before, it may be the browser (tested on Arc browser). This was when I added the date field to a basic page named 'Test basic page'.

I tested on another basic page named 'Hello world', and noticed that the file name of the ICS file was 'Hello world addtolocal.ics'. I thought that was weird, so I renamed the page to 'Hello world page' and tried again, and this time the file was named 'Hello world.ics'.

If this isn't desired, then maybe a bit of work is necessary.

Setup: D9.5.11, PHP 8.1

Thank you both for your testing, and "bump" of priority, I too now have a D10 site that was upgraded from D9, and D7 before that, it is using the add to calendar module and finding the generic "event.ics" that is downloaded with clicking iCal from Firefox is lost in random downloads.

We continue to get requests for this title to be returned as it was in the previous versions.

@Maintainers With the new year on us, can we circle back to another commit? Thanks!

To fix this, I changed the code in addtocal-download.js to this:

Drupal.behaviors.addtocalDownload = {
    attach: function (context, settings) {
      // Trigger file download for any data links generated by addtocal.
      console.log("vor allem");
      $(once('addtocal', '.addtocal-container', context)).each(function () {
        $('.addtocal-link a', context).click(function (event) {
          var href = $(this).attr('href');
          if (/^data:/.test(href)) {
            var title = $('h1').text(); // My node-title
            // var filename = 'addtocal';
            if (/^data:text\/calendar/.test(href)) {
              title += '.ics';
            }
            download(href, title);
            event.preventDefault();
          }
        });
      });
    },

    download: download
  };

Maybe that helps for now.
