Issue: [Bug]: Opera Browser: After a fresh installation from scratch, clicking "Generate" does nothing.
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

To be clear right from the start: I have no problems using Firefox. This problem seems isolated to the Opera browser, and wasn't an issue until I reinstalled the latest version of stable-diffusion-webui. Until today I was using an older version of stable-diffusion-webui that was at least 6 weeks old.

I reinstalled stable-diffusion-webui from scratch on a Windows 11 machine, which was running a previous older version with success. The previous version was completely removed before following the automated Windows installation instructions. The only argument I launch `webui-user.bat` with is `--lowvram`.

The default model loads with no issues. The command prompt output is provided in full under "Console logs":

This is a completely vanilla install, no extensions added.

After that, I launch the Opera browser and type a prompt in as usual, and click generate. The button goes from being a single orange button to being two grey buttons (interrupt and skip) just like normal, indicating the process has begun. But nothing happens. I check the command prompt and nothing is happening there either. It just remains unchanged, as if clicking the button didn't actually trigger anything.

I can still click around the UI, so it's not an issue with freezing. And no error message is displayed. It's just that clicking the generate button does absolutely nothing.

NOTE: Launching Firefox and clicking generate works perfectly fine. For some reason, the latest version in Opera is broken in this regard.

### Steps to reproduce the problem

1. Uninstall an older version by completely removing the `stable-diffusion-webui` folder
2. Install from scratch using [this method](https://github.com/AUTOMATIC1111/stable-diffusion-webui#automatic-installation-on-windows), no more no less
3. Launch webui-user.bat, open the URL in the Opera browser
4. Click the Generate button in text2img
5. Nothing happens, not even an error.


### What should have happened?

It should generate images like an older installation did when clicking the generate button. It doesn't.
