When changing a setting on an site - Example: Setting Dark mode on a subdomain within an iFrame, Webkit is not able to save this setting between sessions. If I go to the subdomain directly and change the setting, It is able to remain saved across reboots. Example sites: Organizr as the main site with Homarr as the iFrame (dark mode option on the hamburger menu)

Hi! What technology are you using to “save” here? WebKit partitions HTML storage per top frame site and partitioned storage is ephemeral. Ephemeral means in-memory-only.

Actually partitioned per top frame *origin*.

I'm using save in a figurative sense. I'm mostly just choosing the dark mode option. Then closing and re-opening a web app/& standard web (using webkit) with iFrames in them. But when going across the iFrames those manually set to dark mode are being reset. I'm using iFrames because it's a control panel. (Organizr) Can iFrames be saved too? Or at least a preference to be saved?

Could you provide a code snippet of how you save dark mode in the iframe, please?

There's a hamburger menu on the top right, 3 lines. if you click the 3 lines, there's an option that says Switch to Dark Mode. There's a demo site for homarr: https://demo.homarr.dev/ Again just hamburger menu on the top right. Thank you for following up. The only difference is that homarr would be within an iFrame.
