Resizing Animation and Audio sections no longer snaps to other sections

1. Create a new level sequence
2. Add a skeletal mesh actor to the sequence
3. Add two animation sections to the SKM Actor
4. Drag one section so they are both on the same row with some space between them
5. Make sure snapping is enabled
6. Disable Snap To Interval under Section Snapping (this makes repro easier to see)
7. Enable Snap to Keys and Sections under Section Snapping 
8. Move the sections close together, and confirm that they snap
9. Move the sections again so there is space between them
10. Drag the start or end of one section to resize the section and drag it to the start or end of the other section

RESULT

The sections do not snap. In 5.2 resizing would snap the sections.
