I don't think you ever could put a torch on a half block, so that is nothing new. If you need lighting, you could always use whole block, double slab (only where they would end up as whole block), or temporarily put a whole solid block there (dirt or whatever) and put a Jack'O Lantern (lighted pumpkin) or glowstone on it, then remove the temp block and place the slab.
Torches do work in inverted steps, but beds cannot be placed there (nor on slabs).
It happen to me,kinda annoying

nope.
There used to be a mod (BetterBlocks) that allowed this. But it's been discontinued.
