Field Mapping - Field Name - disallow spaces

[wayfaringrob]

Right now when field mapping, Pro allows input of spaces where they are not allowed, e.g. a field name:

Instead of warning you or simply not reacting to the spacebar (like the Fields view does), it just splits what you typed into the field name and alias separately and destroys your type settings after a few clicks outside the box:

It would be better if it would just leave the type settings alone and not allow spaces or warn you that it's doing this, thanks.

This Idea has been implemented in ArcGIS Pro 3.2. You can no longer type spaces or special characters into field names on the geoprocessing field map control. 

Please check out this blog to learn more about the updates we made to the field map in Pro 3.2.
