MGNLUI-5426 has harmonized dialogs and set their width to be fixed at 740px. That width is too small when using complex layouts. Examples can be found here and on linked tickets.
The M5 UI framework provided an option to set dialogs to be wide and hence take all the horizontal space available:
- When using the
property, the dialog open in wide mode using all available horizontal space (including 20px left/right spacing)
- No changes to flexible height and min. height (as it is with current default dialogs)
