The A320 did not obey a -FL090 ALT constraint, restarting CLB before reaching the constraint waypoint

Departing EIDW 28R, using the PESI2J SID. The A320 levelled off at FL090 after passing waypoint DW991 because the next waypoint (DW122) has a -FL090 ALT constraint. However it recommenced CLB before reaching that waypoint. A pseudo waypoint for the 250/10000 speed limit appeared between these two waypoints and I think that may have broken the CLB constraint logic. A later ALT constraint at -FL230 was correctly respected.

AIRAC 2508 was still current when I flew this today but I see the FMGC says 2509 is active (from tomorrow, Sept 4).
