Whenever I transfer a world from the Legacy Xbox One Edition to Bedrock XB1, all Minecart Chest contents just completely wipe out, the contents show up as empty.

This is an issue both with some worlds I transferred over many years back when Bedrock was newer for XB1, and even doing a fresh transfer today yielded the same issue.

This issue occurred both on Large worlds and on the smaller "Classic" world size, even when the Minecart was in rendering distance from my character on both legacy console and Bedrock.

I didn't see this with regular chests so far, only Minecart chests. This is an issue since around 2019-2020 or so, both with older worlds I moved over at the time when Bedrock launched, all the way to today with a fresh set of worlds on Legacy Console to Bedrock.
