Important: #69137 - Link Wizard popup width and height fields removed¶
Opening links in popups with width/height definition is a very rare usecase nowadays.
For user convenience and to have less clutter in the UI, the width and height fields have been removed. The editor is not able to select a width and height anymore, it can still be entered manually though.
The RTE option
buttons.link.popupSelector.disabled has no effect anymore.
