Subcommand anchored is not effectual when using relative world coordinates in subcommand run

Steps to reproduce the issue

With “anchored eyes“ in “execute“ command, the execution position does not change when having relative world coordinates(~ ~ ~) in “run“ subcommand.

Expected result

For example, typing “execute as @s at @s anchored eyes run summon falling_block ~ ~ ~“ in chat, the falling_block entity should be created at player’s eyes.

Actual result

For example, typing “execute as @s at @s anchored eyes run summon falling_block ~ ~ ~“ in chat, the falling_block entity is still created at player’s feet.
