I have checked the beta changelogs to try to make sure this isn't an already implemented feature in a future version, but I apologize if I missed it.

In the Java 1.13 pre-releases, XP is saved in furnaces when items are pulled out using hoppers and can be retrieved all at once by taking an item out of the furnace. ( https://youtu.be/Ix5eHh_omuY?t=926 )

This is a feature I was excited to hear about, but I cannot reproduce this in my Bedrock game, despite the release of the Update Aquatic for Bedrock.
