Lighting a Nether Portal has a client-side displaying issue

[fluffyloafie]

All the right packets are sent to the client, however, the player who is lighting the portal sees fire at the firing position instead of the block being updated as a Nether Portal block. The issue is client-side, as other players don't have any issue seeing the Portal built correctly. Upon disconnection and reconnection, the Portal is rightly updated and displaying as it should. The issue is seen only on lighting the Portal with a Flint & Steel.
