fix/feature [#35085] Loop cut slide

Loop cut slide now works with multicut.

issue is that since edge slide now supports more configurations, cases where loop-cut-slide silently failed before,
now slide (albeit in an awkward way at times).

Fix this my adjusting the selection of after loopcut so edge slide can properly operate on it.
