if the portal is a normal portal (e.g. a 1x1 portal into a 1x1 portal) the bounding box will just vanish at some angles
if the portal is tilted forward or backwards, then it will just vanish at some angles.
if the portal is tilted any other way (left/right or side-to-side), the bounding box will just show in random places in the world at random angles.
Is it a mod compatibility issue?

Describe the issue
This issue only occurs with a portal in view
if the portal is a normal portal (e.g. a 1x1 portal into a 1x1 portal) the bounding box will just vanish at some angles if the portal is tilted forward or backwards, then it will just vanish at some angles. if the portal is tilted any other way (left/right or side-to-side), the bounding box will just show in random places in the world at random angles.
