erl_syntax:set_pos/2 or erl_syntax:revert/1 is not works as expected

Describe the bug
erl_syntax:set_pos/2 or erl_syntax:revert/1 is not works as expected

Node = {atom, 20, a}.
Node1 = erl_syntax:revert(erl_syntax:set_pos(Node, 10)).
?assertEqual({atom, 10, a}, Node).

assertEqual above fails.

Reason
erl_syntax use a wrapper to wrap erl_parse tree and erl_syntax:set_pos/2 only changes #wrapper.attr in wrapper record
while use erl_syntax:revert/1 #wrapper.attr is dropped, original pos in erl_parse tree is not changed

Affected versions
OTP 23 and higher

I believe that this is solved by #7398

In OTP27, the assertion above succeeds.
