Snippets: Track begin of first selection

Browse Source 
Since in the snippets overlay the selections are created with
ExpandBegin the interest is mostly in detecting when the first one
moved to the left (for example, when an undo is performed right
after inserting the snippet). However, this tracking doesn't need
to necessarily be associated with that flag.
