We have a few web apps that uses the appcache to store the application offline, we've occasionally encountered an issue when downloading the app, Safari issues a prompt asking permission to increase the local storage to 50MB. Clicking ok causes Safari to just crash. In other versions of iOS (8, 9) this is not an issue, according to a stackoverflow post about this same issue.

Has this been fixed or is there a fix in the pipeline for this?
