"Add Record" in the DNS webUI brings a new empty form after creating a new DNS record. Pressing the back button on the browser returns to the previous empty form. It should return to the previous list.
As a reference, the behavior works as expected in the "Add Web Domain"
Also applies to "Add Mail Account" in mail section the issue is caused by the javascript:window.history.back(); instead of /list/domain?domain=test.nl
Noticed also that list_search has the same user but probably changing would be more difficult...
Thanks for the issue report @vestacp-user, the appropriate fix has been merged for inclusion.
