WebSQL on iOS fails with a quota error

[zspitzer]

if you try to do a few 5MB items on iOS 9.3.1, you get a increase database prompt, followed by an alert with a quota error

{
code: 4 error
message: "there was not enough remaining storage space, or the storage quota was reached and the user declined to allow more space"
}

seems you currently can't increase the database size beyond the initial size specified in the openDatabase call. I have reported this to apple radar://25819252

I have also filed this in the public webkit bug tracker
