In the RELEASE file, it tells you about SHOPT_EDPREDICT, added 10-05-20,
which affects any line that starts with a '#', not just a line being
recalled from history.
10-05-20 +The compile option SHOPT_EDPREDICT has been added. When this
option
is on, as you type a line beginning with a # the following
characters
are treated as a shell pattern and cause matching lines from the
history file to be displayed as a numbered list as you type.
You can scroll up and down this list or you can use <ESC>nTAB
to make this the current line (n defaults to 1 of ommitted) or
<ESC>n<cr> to execute.
I get the same behaviour as you, which certainly seems like a bug - you
are not typing a line that begins with #.
In the mean time, either comment your lines with space hash (" #") or
recompile with SHOPT_EDPREDICT=0
