This seems to be a problem with spawning mechanics in general to me. Chunks seem to save mob data that takes up mob cap, or because the realms render distance is so low, there are mobs around that you can't see that are taking up the mob cap, therefore stopping the much less common wither skeleton and blaze spawning inside the nether fortress. This is a fundamental issue with the way spawning is handled in the Bedrock Edition.

I can get wither skeletons and blazes to spawn if I make circles around a nether fortress, killing any mob I see to increase the chances of wither skeleton spawning, and finally after nearly a month of playing and checking fortresses several times a day, I got my 3rd skull.

I can also confirm this is happening in 1.2.8. enchanted diamond with elytra. Playing realms between win10 and xbox one.

It seems as though after the most recent update to 1.2.8, I got a round of spawns in each of the nether fortresses I've explored, and slimes in a nearby slime chunk, after unloading the chunks, the chunks continue to have no spawns.

Similar issue here. Can't seem to get any sort of nether spawning to happen in chunks that have been unloaded then reloaded. Newly discovered chunks don't seem to have this problem. All nether spawns cease after the chunks have been reloaded, save for 1 or 2 pigman occasionally, which I kill on sight. Slimes seem to be non- existent as well in chunks where they were previously found. Very frustrating to have features of the game inaccessible due to this. Playing on realms server with 4 people regularly on xbox one and win10.
