Broken webstorage pervent user to comment

I had my firefox's webstorage corrupted, this throw an error ( NS_ERROR_FILE_CORRUPTED ) and prevent me from commenting in gitlab 7.8.2.

Even if it's "my fault" (resting the firefox's webstorage fixed the issue), Gitlab should catch the error and fallback to old commenting (I assume this is dues to - Prevent losing unsaved comments by automatically restoring them when comment page is loaded again.).

Thanks !
