[SA 7.1.228 Pro] - Inconsistent name matching for MySQL

I use Name Contains Characters from Key String for Name Matching Method. The popup that follows SET keyword is somewhat inconsistent when it comes to filtering on declared and variables. Compare the following steps with this short video:

1. SET with filtering on user variable works.
2. SET with declared variable works when typing the start of its full name.
3. based on what happened with 2, it seems that SET with declared variable works similar to using Name Starts from Key String method instead of Name Contains Characters from Key String (and the matching text isn't highlighted)
4. Typing the initial @ after SET and then backspacing it leaves the popup open and filtering on declared variables works as expected.
