How to make sure an item bought after security will make it through the connecing airports checkpoints?

During a recent trip, I bought a snow globe in a typical airside (after security) airport shop. It is a souvenir item, not a duty-free thing at all, therefore is was not placed into the well-known sealed bag.
Later during the trip, I had to change terminals at LHR using the airside shuttle - and go through security again. At this checkpoint they nearly discarded the globe as it is obviously filled with water. I told them it was sold at an airside shop. They asked me to make sure that it is put in a sealed bag next time. During the transfer, the other bag was checked until destination and no baggage claim was available to get access to it anyway.
Is there a way to be sure an item we buy during the trip will make it to the destination? Should I ask the souvenir shop to seal some kind of items?
Another thing coming to mind is also, can we know in advance if a particular airport will require us to go through security again during an airside connection?

I had a similar experience from Tokyo -> Chicago -> Philadelphia. At Chicago, I forgot that the snow globe was in my bag. The bag alarmed, the security officer carefully unwrapped it, and told me I needed to check it.
If possible, bring a bag with you that would not matter if it was delayed (don't put keys, medicines, valuables, phones, or passports in it), and when you reach the connecting airport, put the snow globe in it and ask to check the bag to your final destination.
