Some forms displayed in modals doesn't have buttons anymore

I have the same issue :(
I was trying to disable this new feature (which is great, if it would work on modal forms) by disabling option "Enable sticky action buttons" in Gin settings. However disabling this option didn't change anything.
For now, only option I found to make those modal forms work was downgrading gin to RC10

I think this is the same as #3455080 🐛 Save button missing in modal for editing media using Media Library Edit module Fixed

I already have created a MR there, spare some time to test it?

Just tested in linked issue. I think this one can be closed as Duplicate?
