"unblockcomment" incompatible with "automatically remove trailing spaces"

[llan-ml]

Description of your problem

What steps will reproduce the problem?
For example, there are codes:
"""
import numpy as np

def test():
return 1

test()
"""

1. Enable the feature "Automatically remove trailing spaces when saving files"
2. blockcomment (ctl+4) the piece of codes above
3. save the file (ctl+s)
4. unblockcomment (ctl+5)

What is the expected output? What do you see instead?
The expected output is
"""
import numpy as np

def test():
return 1

test()
"""
However, we see
“”“
import numpy as np
# def test():
return 1
# test()
”“”
Please provide any additional information below
It seems like the enabled feature (removing trailing spaces) removes the newline character when saving the file.
