If extdebug really does imply functrace, then that's missing from the documentation. The rest appears to be working as intended.
Look at item 5.
extdebug
If set at shell invocation, or in a shell startup file,
arrange to execute the debugger profile before the shell
starts, identical to the --debugger option. If set af-
ter invocation, behavior intended for use by debuggers
is enabled:
1. The -F option to the declare builtin displays the
source file name and line number corresponding to
each function name supplied as an argument.
2. If the command run by the DEBUG trap returns a
non-zero value, the next command is skipped and
not executed.
3. If the command run by the DEBUG trap returns a
value of 2, and the shell is executing in a sub-
routine (a shell function or a shell script exe-
cuted by the . or source builtins), the shell
simulates a call to return.
4. BASH_ARGC and BASH_ARGV are updated as described
in their descriptions above).
5. Function tracing is enabled: command substitu-
tion, shell functions, and subshells invoked with
( command ) inherit the DEBUG and RETURN traps.
