I just gave it a try from a 21.02-rc1 based config and it looks fine. 
One note: I made PR https://github.com/openwrt/luci/pull/5086 to include a 
hint, that the conversion-dialog might come up multiple times. This will 
prevent confusion of the user, which might expect an endless loop when the 
dialog comes up the 2nd time.
