Stacked written books, bundles, shulkers inside of chests causes massive performance decrease and chunk data size

Hello,

As the issue suggests, there is a specific interaction with nested bundles/bundle item that should be looked at. Whether or not this is intended is unknown to me.

To replicate :

• Fill a 'written book' with UNICODE characters [100 Pages]. Whether or not the increase in data can be done with normal characters is unknown to me, I've been too busy to test this.
• Make 16 copies. Sign all 16 'written books' differently (1, 2, 3, . . . etc.).
• Put said books into a bundle, and repeat this process until you have 27 book bundles.
• Put said book bundles into a shulker box, filling it.
• Repeat making these shulker boxes and filling them inside double chests.

The more double chests with these 'nested shulker box book bundles', the more data that is written to the chunk file. Just six double chests increased one of my files to 65Mb. Attempting to place multiple chests reduces the pc performance of the user (assuming singleplayer), due to the amount of data that is being written.

Multiplayer compatibility is untested; however, it should work similarly.

I thought I'd bring this up since it could be used maliciously to overload a servers data storage. I'll make a more detailed video showcasing the process both in singleplayer and multiplayer if this is not a duplicated issue.
