When returning from the nether into the overworld bad omen effect is removed.

To create.
Travel to pillager outpost via nether tunnel.
Kill banner man and get bad omen.
Travel back into nether and bad omen is still there.
Return to overworld and bad omen is erased upon entering overworld.

Expected results.
Bad omen should stay active when travelling through portals.

Actual result.
Bad omen is wiped when you travel through the portal that brings you back to the overworld.

Edit - Just remembered I turned off render clouds and fancy graphics to try and reduce lag in my world. Just incase this has anything to do with it.

Additional comment: Would love to load up the 30 second video captures of my bugs from Xbox but file size is always too large for your bugtracker despite being the shortest duration possible on Xbox. Please increase the file size limit to accommodate 30 second captures from Xbox users. Videos may contain answers to these bugs that we as players don't spot, bit you as devs might.
