The Table Columns embedded list formatter used in the Tables module for dictionary entries produces unexpected behaviour when the Add Sort filter button is clicked.
Steps to Reproduce
Navigate to System Definition > Tables.
Open any record and click the Filter icon in the Columns tab in the Table Columns section.
Click Add Sort to sort the embedded list.
A new record form is displayed rather than the ability to sort the list. Note that this issue does not occur on a related list.
