It should be done for both in same places and using same logic. If it
currently does not work for InnoDB that needs to be fixed as well.

I've included these ones on places where they should be needed, still
might need some adjustments for AJAX (though it's not dynamically
attached anywhere, so I don't think there will be a problem).

Merging third party scripts will cause problems on upgrading them, but
maybe this is something what could be done on release time (similar to

4s sounds definitely too much.
