Any known issues related to WorldCopyJump w/ Leaflet 1.3.4?

[Tmodurr]

Recently upgraded from Leaflet 0.7 to 1.3.4 and have seen that the previous capabilities in our app drawing geometry over the dateline/anti-meridian have been disabled some how.

Not seeing any thrown errors so wondering if this is either a capability issue or perhaps a difference in the way the WorldCopyJump parameter is accessed in Leaflet 1.3.4?

I've attached the declaration for the WorldCopyJump parameter below.

Specifically looking for features that previously rendered over the dateline/anti-meridian but are now just contained to the "original" world
