For our BEEFY-powered bridge, we need to determine the relay chain block in which a parachain header was included. It seems this happens roughly 2-3 blocks after the relay chain block which backed the candidate.

I was wondering if there is some limit on the maximum block gap between backing and inclusion? For example, could the candidate ever be included like 20 blocks after it was backed?

Knowing this limit if there is one would help improve our code for determining the inclusion block number.
