Important: #85689 - Replaced default value with placeholder in external url link handler
See forge#85689
Description
The Url
in EXT:recordlist used a default input value "http://" for external links.
This is not practical because editors often paste a link in the field. This caused broken links due
to duplicate HTTP protocols, for example: http://
A placeholder is now used instead of a default value. Editors can paste links directly and do not have to remove a default value first.
