Summary:
Bone mealing an azalea/ flowering near 2 tall blocks (solid or transparent) prevents it from growing into a tree (whether the block is right beside it or diagonal)
Blocks that prevent azalea/flowering from growing:
Sugarcane (2 tall)
Bamboo (2 tall)
Extended Piston Head
Double Tall Grass
Large Fern
Twisting Vines (2 tall)
Small Dripleaf
Big Dripleaf (2 tall)
Lower Half Slab (on the second block)
Trapdoor (on the second block)
Stacked Signs On Top
Glass Blocks
Any Soild Blocks (2 tall)
Pointed Dripstone (2 tall, bottom)
Stacked Carpets
How To Reproduce:
Grab a azalea/flowering azalea.
Choose any listed for testing.
Place it right beside the azalea/flowering azalea or diagonal.
Now bonemeal the azalea/flowering azalea.
Observed Results:
The azalea/flowering consumes the bonemeal but doesn't grow into a tree.
Expected Results:
Azalea/flowering should grow into a tree.
Note:
I don't know if this is intentional or not.

The underlying issue for most of the cases here is that any block placed diagonally above any sapling will prevent it from growing, see MC-228758. This is technically an issue with every kind of tree in the game, but Mojang have decided that the behavior is only unintentional when it comes to azaela trees for some reason (MCPE-166948). I have requested that they review that report in hopes that they change the resolution, as fixing this solely for the azalea would create further disparity, not only with Java, but Bedrock itself.
Pretty sure this should be intentional. Above the azalea bush, there are two layers where it checks in a 3x3 area (centered on the bush) for obstacles; it should ignore dirt and leaves. Maybe there's something else it ignores. Further above those two layers, there are three layers where it checks for obstacles in a 5x5 area. (Additionally, there are some other spots where it checks for obstacles for branches, but either way the main bush would grow if the above spots are air, dirt, or leaves. Only dirt, by the way, not coarse dirt or rooted dirt.)
