We are also facing same problem as mention in https://www.flexmonster.com/question/height-of-fields-popup-need-to-be-adjusted/
Did you added any support in recent upgrades? Or Can you please suggest any workaround other than pre-defining its height by using CSS.
Thank you for reaching out to us.
Our team wants to inform you that no updates were made on this point.
We will let you know in case something is changed.
Also, no other workaround than CSS overwriting is known at the moment.
Do not hesitate to contact us in case other questions occur.
