Rule separator positions change when deleting multiple rules
When deleting rules around a separator at the end of the ruleset, separator positions can change unintentionally. Similar to #6801 but doesn't appear to be identical.
I was only able to reproduce it when removing the last few rules of an interface ruleset. If I deleted single rules or multiples around/between higher separator bars, there was no issue and things stayed in the expected places.
See attached before/after photos to see how to reproduce it.
