Stop bubbling up events when removing a choice

[piotr-cz]

Fixes #3209

I've tried also changing the original click event listener to exclude .select2-selection__choice__remove child, but I didn't figure how.

Anyway preventing event to bubble up to main container seems to be cleaner solution.

We are using Select2 as a filter in SPA when changing options triggers re-rendering view with filtered items. When options is removed, options container opens up and when view re-renders options container jumps out to upper left corner and detaches itself from main container.

By the way: what about a new release?

With 4.0.0 we're trying our best to avoid breaking backwards compatibility in the future, and we actually designed how events propagate to allow for others to pick and choose how they want Select2 to work. This was one of those places, which is why originalEvent is being passed into the select2:unselect event.

Anyway preventing event to bubble up to main container seems to be cleaner solution.

I definitely agree, and luckily you can do this without modifying the Select2 core as seen in #3209 (comment).

Working on it, I've been pretty busy in the last month with non-FOSS things.
