block_state_property predicate not working

Trying to use this command (while within a wheat block) to detect whether a wheat block is at age 7:

/execute if predicate {condition:"minecraft:block_state_property",block:"minecraft:wheat",properties:{age:"7"}} run tellraw @a "hi"

and it doesn’t work. Nothing is printed in the chat.

If I try this command instead, it does work:

/execute if block ~ ~ ~ wheat[age="7"] run tellraw @a "hi"

A location_check predicate also works:

/execute if predicate {condition:"minecraft:location_check",predicate:{block:{blocks:"wheat",state:{age:"7"}}}} run tellraw @a "hi"

So the problem seems to be with the block_state_property predicate. I attached a video showing me using these commands.
