I have not looked at this more closely, but:

This is from the Signals and Error Handling section of the SUS:

When a signal for which a trap has been set is received while the
shell is waiting for the completion of a utility executing a
foreground command, the trap associated with that signal shall not be
executed until after the foreground command has completed.  When the
shell is waiting, by means of the wait utility, for asynchronous
commands to complete, the reception of a signal for which a trap has
been set shall cause the wait utility to return immediately with an
exit status >128, immediately after which the trap associated with
that signal shall be taken.
