ACL and STP

when I apply a "permit all packets" rule, I get the warning:
Note: An unconditional PERMIT action on an EAPS or STP blocked port will result in a loop. Adding an explicit match criteria such as ethernet-type will avoid these rules matching EAPS and STP PDUs.
when I use the rule
entry R1 {
if {
ethernet-destination-address 01:80:c2:00:00:00;
} then {
permit;
}
}
the Extreme is happy. But, does STP really work as expected?
If not: How can I use STP with an ACL with the last rule "deny all packets"?
