@bbildman Have seen the problem occasionally and just use the right-click menu to select the <search>-<search with>-<copy> function I wish to use. More versatile.
I created an additional search url to be used for map searches using the <search with> function. i.e. Search engines-Site search-Add
:Search engine: gmaps
:Shortcut: m
:URL with %s in place of query: https://www.google.com/maps/search/?q=%s
snapshot still works with the <ctl><shft><5>
