[Closed] Repairing an Altura Crosslite jacket

I got myself one of these jackets off the classifieds. The corner of the pocket has started to come away from the jacket itself, maybe 1 inch or so has lifted away slightly. I want to repair it as I dont want it to get snagged and rip the jacket.

It seems they have used some kind of glue instead of stitching in the original construction.

Ive got some superglue but have concerns that it might damage/burn the material and render the jacket useless. Has anyone done any similar repairs before? What kind of glue have you used?
