IOS16 Browser: LocalStorage is cleared after writing data of more than ~2.5MB

IOS16 Safari: LocalStorage is cleared after writing data of more than ~2.5MB.

After upgrading to IOS 16 we faced the problem of clearing data in localStorage.When we try to write data that size is more than ~2.5MB or all amounts of data more than ~2.5MB the LocalStorage is being cleared without any errors and warnings in Safari. I could not reproduce the problem in other browsers or platforms.

Step to reproduce:

• Go to IOS 16 Safari
• Open any website
• try to write data more than ~2.5MB (the attached
  defineMaxSizeLs.js
  test script helps you to display the problem)
• check your localStorage

Actual result: your localStorage is empty

Expected result: your localStorage should be filled your data or it should be thrown an exception if the quota is exceeded

Please consider the problem ASAP.

Thank you in advance!
