"Stop processing subsequent rules" option not taken into account when action is "Discard"

[travier]

If I create a rule and use the "Discard" action and select the "Stop processing subsequent rules", I get:

# Rule: Foo
if header :contains "From" "foo-bar" {
    discard;
}

When I should get:

# Rule: Foo
if header :contains "From" "foo-bar" {
    discard;
    stop;
}

like I get for all other rules I've tried with other actions.

Manually adding a "Stop processing" action at the end of the list works but is unexpected.

I would remove 'discard' from:

if (!lastAction || !['stop', 'discard', 'reject'].includes(lastAction.type)) {
