Your question's flawed, like asking someone if they still had sex with neighbor's pets.
Something that was never true can't be "Is it Still true?"
Items that are blessed or insured always stay with you, period. There was never a time I can remember, at least since Insurance was introduced, where being in a container within your pack STOPPED the insured items from staying with you. The container stays with your corpse, but the items will be in your main pack when you rez, even if they were in the innermost of 20 nested containers. In fct, thre's been times I wished some things WOULD stay in their nested container, such as Treasure maps (which are blessed, after decoding, and if you die doing multiple T-maps, your backpack becomes a mess when you rez).
The only exception might be if you get hit by the insured/blessed item bug, where something causes all or part of your insured or blessed items to not come with you when you die - but the Devs have never been able to successfully reproduce that rare error with any regularity as to figure out the cause, and if any cheating script-monkeys know, they aren't about to tell EA the information they need to eliminate that bug. And, that bug hits worn items, stuff in packs, and stuff inside containers within the pack, fairly evenly.
And, if you soak your Talismans in Ensure, won't they be a bit sticky, and start to smell after a while?
