Because of cross-browser compatibility concerns, jQuery's selector
engine makes using :has selector relatively slow. This is usually
acceptable, but in the case of snippet options, some options also need
to use :has in their data-target selector, and nested :has selectors'
performance degrade exponentially with the level of nesting.
Additionaly, jQuery evaluates complex selectors right-to-left, which
makes the :not operator quite inefficient.
Because of that, this commit removes :has and :not from the conditions
that were added at the end of the data-selector, and speeds up the
selector by a factor of ~15-40
Lastly, the addDropSelector options was actually unused, and a leftover
from the editor revert, as such it has been removed.
