When applying workflow on forms, if you select entries and you want to apply an action (Refuse, Ask complements), a popup is opened for email sending (if email action set on workflow action).
The Problem is that the checkbox "Email sending" which is at the top of the popup is not ticked and all field of the popup are available.
If we try to tick it a first time, it doesn't work and all fields become disabled.
If you try a second time, it works.
It is just the initial state of the checkbox which is not correct.
