Definitely no doubt about it, great catch.
I think it was an out, from what I read in ASA rules.
Rule 1 - Catch -
C. The fielder's feet must be within the field of play, touching the "out of play" line or in the air after leaving live ball territory in order to have a valid catch. A player who is "out of play" and returns must have both feet touching the playable area or one foot touching and the other in the air, before the catch is legal.
Reading this rule and the others, IMHO, the ball was in her glove right before her feet hit the fence.
