return exit code in EXIT trap

[Robert E. Griffith]

Is it known behavior that return without a parameter will not set the 
exit code from the last command when called from the EXIT trap?

   $ cat -n exitReturnBug.sh
         1      #!/usr/bin/bash
         2      function shouldReturnFalse() {
         3              false
         4              return
         5      }
         6      trap 'shouldReturnFalse && echo "woops"' EXIT
   $ ./exitReturnBug.sh
   woops
If I change line 4 to "return $?" it will not print "woops" which is the 
correct behavior.

I tested this in 5.0.17 and 5.1.16.
