Exposed filters are not inherited in attachment display

#21 worked for me as well.
I also tested this by attaching to a page and not a block display.
Thank you!

#21 works also when the parent display is a block on D10, but needs the patch from the related issue https://www.drupal.org/project/drupal/issues/2171389#comment-14128568 🐛 Attachments on Views Content Panes don't always inherit exposed filters Postponed: needs info

I have experienced the same issue and can confirm that that the patch linked above 🐛 Attachments on Views Content Panes don't always inherit exposed filters Postponed: needs info fixed the problem 💪

Since the other issue 🐛 Attachments on Views Content Panes don't always inherit exposed filters Postponed: needs info is taking care of the same problem and a working patch is there I am closing this issue
