Failed to read the 'localStorage' property from 'Window': Access is denied for this document.

Expected and Actual Behavior

Getting the error: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.
when opening an iframed page using fancytree.
I am not even enabling or using the persitance plugin, its just bundled within the all-deps.js file.

Chrome dev tools clearly show the origin of the error is here:

fancytree/src/jquery.fancytree.persist.js

Line 38 in cf9a7b6

localStorageStore = window.localStorage

Steps to Reproduce the Problem

1. use fancytree in an iframe over different domains
2. make sure the "block third party..." setting is enabled in chrome (https://www.chromium.org/for-testers/bug-reporting-guidelines/uncaught-securityerror-failed-to-read-the-localstorage-property-from-window-access-is-denied-for-this-document) But as far as i can see, this is the default.

Environment

• Browser type and version: Version 83.0.4103.116 (Developer Build) built on Debian bullseye/sid, running on Debian bullseye/sid (64-bit)
• jQuery and jQuery UI versions: bundled with fancytree
• Fancytree version: fancytree-2.36.1/jquery.fancytree-all-deps.min.js

same applies to

fancytree/src/jquery.fancytree.persist.js

Line 51 in cf9a7b6

sessionStorageStore = window.sessionStorage

i simply replace window.localStorage and window.sessionStorage with null as quick workaround for now.

Hi,
could you try if this fixes it for you:
https://raw.githubusercontent.com/mar10/fancytree/master/src/jquery.fancytree.persist.js
(Should display a warning, but not fail.)

is there a jquery.fancytree-all-deps.min.js with this fix already by any chance? Otherwise i will try build my own.

You can try this build:
jquery.fancytree-all-deps.min.js.zip

Just tested the new file and can confirm this. It puts a warning in the browsers console but works fine now.

Thanks
