That's incorrect. A backspace character sent to a terminal device
moves the cursor (or does whatever else the terminal chooses to do
when it receives the character) but has no effect on the input buffer.

For what it's worth, I cannot reproduce this in a simple test. I opened
a new window, and then:
imadev:~$ showsize() { echo xyz; }; trap showsize SIGWINCH
imadev:~$
The function and trap have been defined. Then I resized the window,
and xyz (plus newline) appeared as expected. I typed "echo foo" and
pressed Enter, and got the expected result.
imadev:~$ xyz
echo foo
foo
imadev:~$
This makes me continue to suspect that the problem is being triggered by
something else in your setup (possibly multiple things working together).
You might try to reproduce the problem in a simpler setup, to see if you
can isolate what factors must be present for it to occur.
