Which Umbraco version are you using?
16.3.3
Bug summary
In Umbraco 13 you could drag and drop hostnames to change their order. This was very useful as the top most domain is the default, so if you have a link from one rootnode on the site with one hostname that links to another rootnode with a few different hostnames registered the top hostname would be the one shown.
In Umbraco 16 it appears that it is no longer possible to reorder the hostnames, so to change their order you have to remove and add in the right order.
Specifics
No response
Steps to reproduce
Add multiple hostnames to a node and then try to swap their order.
Expected result / actual result
