[Bug]: WebUI is non-functional only on iPad

[halr9000]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

Main interface will not load at all on iPad. Most times I will see only the "Stable Diffusion" window title, and a blank screen, and page load will stop. (Stop button changes to refresh.) Occasionally, with multiple refresh attempts and after a very long delay (>60s ? So long, it's not worth timing), the SDUX loading screen text will appear, but never progresses past that.

I've had it load from this same device previously, but I had not been running SDUX for some months, so I do not know what may have changed. Suspect it's Gradio, but this is very hard to troubleshoot from mobile device without access to js console. Happy to help troubleshoot though if you have some tricks.

Works fine from multiple PCs, Macs, and Android devices in my possession.

Steps to reproduce the problem

1. Fresh install
2. Start WebUI
3. Load page from PC: success
4. Load page from Android: success
5. Load page from iPad Safari: fail
6. Load page from iPad Chrome: fail

What should have happened?

All the things

What browsers do you use to access the UI ?

Google Chrome, Brave, Apple Safari, Android, iOS

[Note that this output is not from a fresh install, but I have reproduced many times. Definitely some crap in here.]

Interesting! Disabling all extensions actually reverts the UI to upstream, which surprised me, and the page loads fine:

Will test a few more variations.

Here it is with only extra (not built-in) extensions, and it is broken as I expected (adding an update below, it's partially working):

Console (note that some of that cruft comes from built-in extensions):

Update. By disabling extra extensions, it loads -- kinda. As you see in these pics, it is not happy. This is Chrome, but it breaks the exact same in Safari,.

All of the extra network pages say Loading like this:

Extensions tab also fails to load:

[halr9000]

Last update for now, here's the same server with same config as above (disabled extra extensions), working just fine from Android, which is what confuses me so much.

Thank you for your feedback. Unfortunately, I do not have any Apple devices to test. There is an advanced selector that you can check if your current browser supports at https://caniuse.com/css-has.
