Templates do not save when an element has an emoji in it. The save function appears to work but when reloading the editor or previewing the template the template or any changes are not visible.
One of my elements had an emoji and the template didn’t save until I removed it.
Ok, then it should work. There are other collations where it doesn’t work.
