New empty column_break added automatically in form builder

Hello Frappe Team,

I have been using the form builder in the nightly branch and noticed a bug where a new empty column_break is added at the end of a section automatically only when I add 4 columns or more. This causes the section to have one extra column, which is empty.

For example, if I divided a section into 4 columns, it appears as 5 columns with the last one being empty. This behavior can lead to confusion and should be fixed.

I would appreciate your help in fixing this issue as soon as possible. Let me know if there is any further information I can provide to assist in resolving this bug.
