Changing the name of a widget so remove spaces from the name appears to have no effect. If the only changes to a widget's name in the designer tab are to remove/add spaces, the changes will not take place.
Result: The Widget's name does not change (the space remains)
Expected: The name for the widget would change to reflect the removal of spaces
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-59084 in the post.
