Description:

Max length for custom user status is 120. It is defined in status options. But not defined in custom user status add/edit form.
So the issue here is that user can enter a status of any length but only 120 length is visible. So in this way, an important part of status may be trimmed out. But if max-length is defined then they will try to fit the status in 120 lengths only, keeping all the important points within range.

Here max length is defined as 120

Here it is not defined
