Bash will not take them while it's sitting in the call to readline.
Something is indeed messed up in your execution environment.
Let's try killing an interactive shell sitting in readline() from another
terminal:
$ echo $BASH_VERSION
5.2.37(6)-release
$ trap
$ echo $$
30762
User defined signal 1: 30
[shell terminates]
Now let's try killing an interactive shell that's not sitting in readline()
with the same fatal signal:
$ echo $BASH_VERSION
5.2.37(6)-release
$ trap
$ kill -USR1 $$
User defined signal 1: 30
[shell terminates].
