Please do not comment a piece of code. If you want to remove something, just remove it.

I don't know if we should rely on this property or leave it to theme layer.

I think this needs a server-side validation too.

This was already commited, but I liked the more descriptive 'event' variable name.

Please send a separate patch in #789712: Enable option to force selection of parents terms with only their related changes. Also, if you want, submit a follow-up patch in #1114510: Nested taxonomy lists collapse unintentionally with the event variable name changes.

Thank you.
